Ingredient:
1 lemon, sliced
2 tbsp sugar (optional)
​4 cups prepared lemonade, chilled
1/2 cup limoncello, lemon vodka or lemon liqueur

Method:
Pour lemonade into 2 ice cube trays. Freeze.

One hour before serving, rim 2 wide-mouthed pint-sized Mason jars with lemon and sugar.

To prepare, blend frozen lemonade cubes in a hi-speed blender with limoncello.

Add sugar if extra sweetness is desired. If mixture needs to be thinned, add a small amount of chilled lemonade until preferred consistency is reached.

Garnish with sliced lemon. Enjoy immediately.
