1: Peel 4 peaches (use the same method as for tomatoes) and cut into small chunks. Put the chunks into a bowl, moisten with 100 ml sugar syrup and add the mint leaves, after crushing them briefly. Cover and leave to steep for 30 minutes.
2: Remove the mint leaves. Divide the peaches between the dishes.
3: Just before serving, place a scoop of sorbet in each dish and decorate with a little sprig of mint.
Remarks
You can use whichever variety of peaches you prefer: yellow, white, nectarines...
