Makes about 1 quart

Ingredients:
1/3 cup water
2/3 cup sugar
1 medium lemon, preferably unsprayed
2 cups buttermilk
1/4 cup freshly squeezed lemon juice (from about 2 lemons)

Directions:
In a medium saucepan combine the water and the sugar. Grate the lemon zest into the pan. Heat, stirring frequently, until the sugar has dissolved. Remove from the heat and let it come to room temperature, then place the syrup into the fridge until thoroughly chilled.

Whisk the buttermilk into the syrup and then whisk in the lemon juice. Freeze in an ice maker per instructions.
