Peel and slice peaches. Simmer in orange juice with nutmeg (cinnamon might be good too). Puree, adding also as you puree: half large cantaloupe. Taste the resulting 'soup'. Thin with orange juice if it seems too thick, add a touch of honey or sugar if your fruit wasn't sweet enough for your taste. Chill. Serve garnished with handfuls of fresh blueberries.
