Was looking for a recipe that used an ancient bottle of Fragolino liqueur that someone gifted us. Made do with 25ml creme de framboise and 50ml vodka. Omitted the sugar syrup because I didn’t have any - certainly wouldn’t want it any sweeter with the framboise in the mix. Would perhaps benefit with a little added freshness - maybe a sliver of lemon peel in the muddle or as a garnish?
