Limoncello

4. Homemade lemon liqueur is as easy as pie.
Limoncello is a southern Italian lemon liqueur traditionally served cold as a digestif. It’s ridiculously easy to make: Combine ½ cup lemon rind strips with 4 cups vodka, cover, and let stand for two weeks; strain and combine with simple syrup made from 3 cups water and 1½ cups sugar. The higher the proof of the vodka, the more lemon flavor your finished product will have.
