One 19.9 oz. can of lychees has about 1 cup of lychee juice, so you can get about 5-6 cocktails from 1 jar. For a party of 10, I assume folks will want at least 2 of these, so I pick up 4 cans. To make enough for 5 cocktails, mix: 10 oz. sake 8 oz. lychee juice 2½ oz. fresh lemon juice 2½ oz prosecco 2½ tsp. cherry syrup I store the batched cocktail in a glass jar. When ready to serve, pour the cocktail into a cocktail shaker with ice, pour, top with prosecco, and give each glass ½ tsp. of cherry syrup from the jar. If you want to serve this in a punch bowl, pour the sake, lychee juice, lemon juice, and prosecco into the bowl. Then, pour Luxardo cherry syrup into the bottom to give it that bloody effect.
