Crema di Limoncello (Cream of Limoncello)

Wash and scrub the lemons to remove any wax or residue. Remove the peel of the lemons with a vegetable peeler or very sharp knife, being careful to only remove the yellow part, and none of the white pith.

Place the lemon zest in a large glass jar with a tight-fitting lid. Pour Everclear over lemon zest, replace and tighten the lid. Let sit at room temperature in a dark place for at least 2 weeks.

Pour milk and sugar in a large heavy-bottomed pan over medium heat, and heat until sugar is fully dissolved and mixture is hot but not boiling, stirring occasionally. Stir in powdered vanilla extract or liquid vanilla extract. Remove from heat and cool completely.

Using a fine sieve or cheesecloth, strain lemon mixture into milk mixture, removing all of the lemon zest; mix well. Pour into a container that has a pour spout, decant into decorative bottles, and store in the freezer.
