2.3.1 How to Develop your Cook Settings

Cooking with a TurboChef oven is different and exciting! It delivers hot food faster, at a higher quality than other ovens available today.

TurboChef uses both hot air and microwave energy to cook food. If you have experience with either a convection oven or microwave oven you will see similarities and significant differences. The key to creating good cook settings for your food is to understand the following rules of thumb. When you get a list of cook settings you are happy with, write them down and store the list in a safe place.

1.TurboChef uses a moving shroud of hot air to surround the food. This locks in the food’s moisture.

2.The hot air provides coloring and crispness of most foods. The higher the air velocity, the faster heat energy is transferred to the exterior surface of the food.

3.The microwave provides heat to the center of the food. Don’t try to do all the cooking with microwave!

4.The weight of food determines the total time required to cook. The more weight, the longer the time required. (Most medium thick crust pizzas cook in about 100 seconds.)

5.Be careful to balance the use of microwave on thick or frozen products. A tendency will develop to overcook the edges before reaching the desired internal temperature.

6.Microwave seems to work best in the early stages of cooking, then use hot air to finish the cooking. Although a continuous lower level of microwave is beneficial for thick or frozen foods.

7.Color seems to develop mostly at the end of the cooking cycle. Higher velocity air in the later stages of cooking will strongly control the food’s color.

Don’t be afraid to experiment! Write down your current cook settings and then start testing. You can always go back to the old cook settings in a few seconds. Enjoy the power and flexibility of your TurboChef System.
