Remove the hull, or “cap,” from the top of the strawberry with a paring knife or a strawberry huller, a small tweezer-like utensil with rounded ends. To use, grasp the green, leafy hull with the huller, then pull to remove the green hull and the white core without removing any of the strawberry. Look for hullers at kitchen stores, department stores or shops online that carry kitchen supplies. Preparing your strawberries this way allows for less waste of the berry and makes eating and slicing them so much easier.
