This helps redistribute the food and can reduce uneven cooking.

The Basket Release Button must not be pressed during shaking.

Add a Small Amount of Oil to Fresh Potatoes

The manufacturer recommends adding a little oil to fresh potatoes when preparing french fries.

This can improve their crispness.

Use an Appropriate Portion Size for Fries

Approximately 1 pound of fries is identified as the preferred quantity for achieving crispy results.

Check Food Before Serving

Food must be cooked thoroughly before consumption.

If ingredients are not fully cooked when the timer sounds, the cooking pot may be returned to the appliance and additional cooking time selected.
