This is another one that, instinctively, you might think wouldn’t work. But you’d be so wrong. Like pineapple, all the sugar and water in peaches kind of ooze out and caramelize into a sweet, syrupy goodness. If your dad has never grilled peaches for you, suggest it to him. He’ll be amused by the weirdness of the idea…until he tries it, and it suddenly becomes his favorite summertime dessert.
