This is a delightful, refreshing, and refreshingly low-alcohol aperitif that one can quaff all afternoon, before, during, and after a good repast, without alcohol overload. Simple and classic in flavor, one would think it a venerable standby, but it’s actually a recent invention that has taken Europe by storm. A simple mix of Prosecco – or your own favorite sparkling white – seltzer, elderflower syrup and a sprig of mint and lime to garnish. We usually mix glasses by eye at my house – you really can’t make a bad one.
