Instructions

1. In a medium bowl, combine raspberries and sugar. Crush berries with the back of a spoon until mostly liquid, stir, then allow to sit for 15 minutes to dissolve sugar. Using a spatula, force berries through a fine mesh sieve into a small bowl, pressing hard to release as much juice as possible. Discard seeds. Transfer raspberry purée to a large glass pitcher, add lemon zest and juice and limoncello and stir to combine. Top with chilled Prosecco, stir well and serve in chilled glasses over ice.
