Settings

This table below will help you to select the basic settings for the ingredients.
Note: Keep in mind that these settings are estimated settings only. As ingredients differ in origin, size, shape and brand, we cannot guarantee the best setting for your ingredients. Because the Rapid Air technology heats the air inside the appliance instantly, pulling the basket briefly out of the appliance during hot air frying barely interrupts the process.

Tips
– Smaller ingredients usually require a slightly shorter preparation time than larger Ingredients.
– A larger amount of ingredients only requires a slightly longer preparation time, a smaller amount of ingredients only requires a slightly shorter preparation time.
– Shaking smaller ingredients halfway during the preparation time optimizes the result and can help prevent uneven fried ingredients.
– Add some oil to fresh potatoes and fry your ingredients for another few minutes for a crispy result.
– Do not prepare extremely greasy ingredients such as sausages in the air fryer.
– Snacks that can be prepared in an oven can also be prepared in the air fryer.
– The optimal amount for cooking crispy fries is 500 grams.
– Use pre-made dough to cook snacks quickly and easily. Pre-made dough also requires a shorter preparation time than home-made dough.
– Please use a baking tin or oven dish in the fryer basket if you want to bake a cake or quiche or if you want to fry fragile ingredients or filled ingredients.
– You can also use the air fryer to reheat ingredients. To reheat ingredients, set the temperature to 150℃ for up to 10 minutes.
