Make the puree: Toss the chopped peaches, ginger, honey, and lemon juice into a blender. Blend until it’s totally smooth.
Strain the mixture using a fine mesh strainer over a bowl—press with a spoon to get all the good stuff out. Get rid of the solids.
Chill the puree for at least half an hour before you use it.
Assemble the cocktails by spooning 2 tablespoons of the peach-ginger puree into each champagne flute.
Slowly pour the chilled prosecco into each glass. Let it swirl and mix on its own.
Stir gently with a bar spoon if it needs a little help blending.
Garnish with a peach slice and maybe a piece of crystallized ginger if you’re feeling fancy.
Notes
This recipe makes about 6-8 cocktails, depending on how heavy-handed you are with the pour. The peach-ginger puree keeps well in the fridge (airtight, please) for up to two days.Want a non-alcoholic version? Just swap the prosecco for sparkling water or ginger ale. You can play with the sweetness—add more or less honey, no judgment.The ginger flavor does get a bit stronger as the puree sits, so maybe go easy if you’re prepping ahead.
