Lots of recipes say for you to peel the peaches, I don’t, but up to you.
Put the raspberries in a blender with 2 tablespoons sugar until pureed, then refrigerate. Core the peaches and slice into bite size pieces. Dust with sugar and squeeze a lemon slice over, stir and refrigerate.
When ready to serve put the peaches in the bottom of a bowl, put a scoop of ice cream on top, and drizzle with the raspberry puree. Top with an edible flower or mint sprig and call it done.
