tain hygienic conditions at all times.

Use only fresh ingredients of the highest possible

Always exercise the greatest possible care and main-

quality. Prepare raw ingredients properly.

Place the raw, refrigerated ingredients into special
bags suitable for Sous Vide. Vacuum them with a suit­able vacuum device.

Fill the bath tank with hot water and use your Dia-
mond to heat the water to the desired temperature.
When the desired temperature has been reached,
place the bag with the food into the water bath. Cook
gently at low temperatures but for an extended peri­od of time.

If you are unsure about the appropriate temperatures
and cooking times, you must consult a Sous Vide
cookbook.

If you will not serve the cooked food immediately,
you can allow the food to cool down and store it in a
refrigerator.

To do this, interrupt the cooking process shortly
before the normal ending time and cool the food to 3
°C (37 °F) within 90 minutes. The best way to do this
is with an ice water bath or a shock freezer.

Safety notices for Sous Vide cooking

Safety notices for Sous Vide cooking

Only trained experts should attempt the Sous Vide
cooking technique. It is important to follow precise
and uniform work steps and maintain a hygienic envi­ronment in order to ensure adequate safety during
food preparation.

It is critically important to follow procedures that
minimize the risk of the growth of anaerobic bacteria,
such as clostridium botulinum.

Make sure that you are using Sous Vide techniques
from a trained expert or from a technical culinary
manual.

Notice

Please remember to observe the following

 Use high-quality ingredients from reputable manu-

facturers only.

 Separate the areas for raw and cooked food.
 Observe the appropriate minimum temperature

when cooking food.

 Observe the maximum storage temperatures and

storage times recommended by experts or tech­nical journals.

 Label food with the date of cooking and the date

of expiration.

 Always work in a sterile environment and use

sterile gloves when filling the Sous Vide bags.

 Use separate devices for vacuuming raw and

cooked food.

temperature

It is also important that kitchen personnel employ an
appropriate HACCP (Hazards Analysis and Critical
Control Points) system in order to monitor and doc­ument every step the food takes from delivery to

serving.

Monitor the quality of the water in the Sous Vide bath
and change it regularly. Depending on the hardness of
the water, we recommend decalcifying the unit regu­larly. To do this, use a food-compatible decalcifier.

Be aware of potential breaks in the cold chain or
unnecessary food storage time.

Also make sure that the cooked food cools down
within the proper time before placing it into storage
(maximum temperature 3 °C (

37° F)).

To achieve pasteurization, food cooked according to
the Sous Vide process must reach a core temperature
of at least 65 °C (149 °F). It is advisable to use a tem­perature sensor or other thermometer to check the
core temperature.

In all cases, you are responsible for following Sous
Vide regulations enacted by your local health agency
as well as all food-safety directives that apply to your
area of responsibility.

First steps

Prep work

Prep work

This chapter is intended for users with little or no
experience with the Sous Vide cooking technique. If
you are an experienced Sous Vide cook or profes­sional chef, you may skip this and continue with page
30 „Working with your Diamond“.

After installing, connecting, and turning on your Di-
amond, you are probably anxious to obtain your first
results with the unit. The following example includes
step-by-step instructions to ensure that you will be
successful even if you are not yet familiar with the
Sous Vide method.

1. Obtain from your butcher a piece of very high
quality beef (ideally a filet).

2. Cut the filet into slices no more than 4 cm (1 ½

inches) in thickness and vacuum them individually.

TIP

Most butchers have professional vacuum equipment.
For this reason, the easiest approach is to ask your
butcher to cut and vacuum the meat for you.

3. Store the meat at no higher than 3 °C (37 °F)
until you are ready to start
cooking.

25

First steps

Starting the unit

Setting the

Retrieving stored
temperature
values

After all preparations have been completed, you can
begin the cooking process.

1. Make sure that the cooking container is properly
filled and the Diamond is correctly installed and
connected.

2. Switch on the Diamond at the rear of the unit.
The unit will go into standby.

During standby mode, two temperatures are

displayed: The top line shows the selected target
temperature (S); the bottom line shows the tem­perature (I) currently measured in the water bath.

3. Use the arrow keys to set the target
temperature. First set the whole number digit.

Confirm your selection with . Then set the
decimal places. Confirm again with and the

entered value will be used as the target tempera­ture. Pressing the Esc key will take you one

step back into the main view.

4. You may also use one of the preset values to
obtain an adequate temperature for your beef. To
do this, press the "Meat" temperature symbol.
The word MEAT will appear on the display; be­low that you will see preset temperature value 1.
Five different values are stored under each quick
key. Each time you press the quick key it will ad­vance to the next value.

> 62 °C (143.6 °F)

6. To start the unit, press and hold the key for
about 2 sec. The Diamond will start, i.e. the circu­lation pump and heater will function to heat the
water bath to the target temperature.

The display will change while the unit is in opera-

tion: In the center you will see the current tem­perature of the water bath in large digits; the line
below this displays the selected target tempera­ture.

1. After the Diamond has heated the water bath to
the desired temperature, place the meat into the
cooking container.

2. Using the timer function cook the meat for at

least 60 minutes.

Use the timer function: Press one of the timer

keys, use the arrow keys to select the de­sired time, and confirm with .

3. After the time has elapsed, remove the meat from
the cooking container.

4. Open the vacuum package, remove and dry the
meat somewhat allowing it to rest for a few
minutes.

Improving the results

The results of the cooking process are influenced by
many factors, including:

• The quality of the meat

• The cut of meat

• The thickness of the individual pieces of meat

• The precise temperature, cooking time, and

taste?

What can I do
better?

For these reasons, it is unlikely that you will achieve
optimal results the first time you use the unit. To
improve the results over time, you should ask your
guests for their honest opinions and request their
suggestions for improvement, for example: Was the
meat too rare? Was it overcooked? You will have to

experiment to achieve the best possible results.

The best way to do this is to take accurate notes on
your preparations and cooking conditions. This will
allow you to successfully reproduce dishes and avoid
making the same mistakes twice.

sides in order to achieve an attractive brown col­or. Then serve.

28

Improving the results

How can I

influence the
results?

Now that you know how to use your Diamond,
careful manipulation of two major variables can influ­ence the cooking process:

 Cooking temperature
 Cooking time.

The following chapter explains how to adjust the
temperature and monitor cooking time. This infor­mation will allow you to gather a few initial experi­ences. We also recommend referencing a compre­hensive Sous Vide cookbook in order to more fully
understand the relationships between temperature,
time, and results.

If you wish to precisely monitor the cooking process
and your results, try using a core temperature sensor.
This is described in more detail in the chapter titled

A closer look starting on page 37.

This displayed temperature will be adopted as the
new set point.

Changing the stored temperatures

After you have more experience, you may wish to
store your own temperature values. You can do this
in two ways:

 Retrieve the stored values and adjust them or
 Store the current target value in the

desired location, thereby overwriting the old val­ue.

Adjusting stored temperature values

Adjust a stored temperature value as follows:

1. Press the quick key under which you wish to
store a value.

2. Select the desired location by repeatedly pressing
the quick key or by pressing the arrow keys

.

3. Press and hold for at least two seconds to
confirm the selection.

4. Use the arrow keys to select the desired temper­ature value and adopt that value by pressing .

The new value will be stored at the selected location.
Doing this will not change the current set point.

32

Storing the current set point

If your current set point is the optimal
temperature, you can easily store this temperature so
it can be retrieved later.

Assume, for example, that you have determined that a
temperature of 59.6 °C
perature for your beef filet and you wish to store this
temperature in the unit's memory. The temperature is
still selected as the set point.

(139.3 °F) is the perfect tem-

1. While in the main view, press and hold the de-

1 59.60

sired quick key for at least two seconds (in this
example: the Meat key).

Quick key 1 will be displayed; only the number

will blink.

2. Use the arrow keys to select the desired
storage space and then press .

The current temperature set point will be
stored at the selected location.

Working with the timer

The Diamond has three timers that operate com­pletely independently of each other. If a timer is ac­tive, the corresponding key will illuminate. All timers

Working with the core temperature sensor

To achieve the most precise results possible with the
Sous Vide technique, you will need to use the optional
core temperature sensor. Simply connect the core
temperature sensor to the socket on the rear of your
Diamond. Then insert the tip of the core tempera­ture sensor into the food being cooked, so you will
know the exact core temperature of the food at all
times.

There are two different ways to approach this meth­od:

1. As soon as the meat reaches your desired core
temperature, you can consider it fully cooked and
serve it immediately.

2. Once the core temperature has been reached,
the meat must be cooked for an additional speci­fied time in order to comply with the relevant
HACCP safety regulations.

the desired core temperature is reached; you can
then continue preparing the cooked food.

Connecting the core temperature sensor

We recommend using only the fusionchef by Julabo
core temperature sensor, which has been calibrated
at our factory and is designed to work with precision.

1. Plug the core temperature sensor's cable into the
proper Pt100 socket on the rear of the unit.

Notice

Although the core temperature sensor is inserted
into the vacuum bag through the special adhesive

food will come into contact with liquid from the wa­ter bath. For reasons of hygiene, do not serve food
from the bag into which the core temperature sensor
has been inserted. Instead, use this food as a refer­ence or retention sample only for pieces of the same
food of equal size.

1. Place a piece of adhesive sealing tape onto the
vacuum bag.

2. Insert the sensor through the sealing tape and
into the food so that the tip of the sensor is at
the center of the food.

Exercise caution in order to avoid puncturing the

other side of the bag.

Automating processes

Using automatic cooking time detection

If you are a professional chef and would like to
achieve consistent results with the Sous Vide tech­nique, you will benefit from cooking time detection.

Cooking time detection utilizes a temperature sensor
alarm that you have recorded set. As soon as you
have determined the optimal cooking time (with the
aid of the core temperature sensor), you can store
the required cooking time under any of the timers.
This will make the time accessible whenever you use
that timer.

By using this stored cooking time you will produce
consistent results for that item without using the core
temperature sensor. You simply use the cooking time
that you stored in the timer.

between these two events is stored as your cook­ing time.

4. However, you decide that the meat has not been
adequately cooked. Therefore, you temporarily
mute the alarm.

5. After the specified time passes, the alarm acti­vates once again. The time that passes between
muting and re-activation of the alarm will also be
added to the cooking time. The same applies to
every subsequent muting of the alarm.

Automatic temperature monitoring

Using automatic temperature monitoring

Our units are designed to achieve a precise target
temperature in the water bath. Temperature changes,
like those caused by the addition of refrigerated food,
are quickly compensated for. However, certain condi­tions such as the adding cold water to the water bath
may result in larger temperature fluctuations.

Automatic temperature monitoring gives you the

ability to precisely monitor the target temperature

and stay informed of any temperature deviations. An
alarm will activate when the temperature in the water
bath deviates from the target temperature by a speci­fied amount.

Setting temperature limits

1. To access the menu, press the Esc and sen­sor keys simultaneously.

2. Use the arrow keys to select the CON­FIG menu entry and confirm with .

3. Select TEMPMON and confirm with .

4. Instead of the OFF entry, select the specified
number of degrees.

The number of degrees indicates the

range in which the water temperature may fluctu­ate above and below the preset value before trig­gering an alarm. For example, if the target tem­perature is
60 °C (140 °F) and the range is set at 0.5 °C
(33 °F), then the temperature may fluctuate from

59.5 °C to 60.5 °C (139.1 to 140.9 °F).

Activating temperature monitoring

Temperature monitoring is switched on as soon as
you set the temperature limits in the menu. However,
it is fully activated only once the specified target tem­perature has been reached. Temperature monitoring
is deactivated while the unit is heating up (or cooling
down).

This applies also when the target temperature is
changed:

If a new target value is entered, temperature monitor­ing will be deactivated until the new target tempera­ture has been reached.

Once the target temperature has been reached with
the temperature monitoring activated an audible signal
and alarm message will display every time the temper­ature exceeds the specified range.

Care and maintenance

The circulator is designed for continuous operation
under normal conditions. Regular maintenance is not
required. A particle filter protects the circulation
pump from large contaminants in the thermal bath
fluid. However, you should perform the following
cleaning tasks each day.

Changing the water

The circulator is suitable only for use with sof­tened/decalcified water. The water in the stainless
steel bath should be changed regularly.

Our recommendation:

Change the water daily

for the following reasons:

• Frequent refilling increases the concentration of

minerals in the water, which can form a crusty
deposit inside the bath and on immersed parts of
the circulator.

• Dirty vacuum packaging can release particles into

the warm bath water.

Changing the water

Draining combi units

Use the integrated drain tap to empty a Diamond
XS, S, M, L, or XL combi unit.

1. Switch off the unit and pull the mains plug.

2. Place the unit over a sink or a container large
enough to hold all of the water.

3. Open the drain tap and allow the water to flow
out.

Decalcifying

Depending on the hardness of the water, we recom­mend decalcifying the circulator regularly. To do this,
use a food-compatible decalcifier. Please refer to the
manufacturer's instructions for the exact procedure.
