Hulling strawberries: there is a good way to do this and a bad way to do this. The bad way involves cutting off the top third of your strawberries. The good way involves removing the leaves and stem top without sacrificing a lot of fruit.
Get a sharp paring knife and cut into the strawberry just under the leaves, angled in toward the middle of the berry. Turn or roll the strawberry as you cut, cutting a tiny cone-shape out of the top of the berry. Repeat.
