1. Remove the peel
Carefully remove the peel and then cut the onion into half lengthwise from the root to the tip. Important: Do not remove the root of the onion! Place one half of the onion on the chopping board with the cut surface facing downward. Small tip for ideal handling, so that you do not cut yourself: Position your fingertips slightly bent on top of the onion. This means that the knife can be guided easily along your fingers.
