“Grilled peaches may be summer’s greatest joy.” —Sam Sifton
Grilled plums too, Sam, grilled plums too.
Approximate quantities: 4 peaches or plums, halved; 4 teaspoons of raw sugar, approximate 1 teaspoon per of fruit; cinnamon
Cut the peaches along their seams, all the way around, and then twist the halves off of the pits, place in a large, rectangular Pyrex baking dish or on a sheet pan skin side down, sprinkled with sugar and cinnamon
Place on the grill skin side-down and grill on medium heat for about 10 minutes, turning them half way through
Serve with ice cream or basil whip cream!
The variable here is your grill and it’s temperatures. I’ve provided a heat and time range for everything that should work for almost all grills.
Almost everything needs to be turned, or if it’s in a grill basket a good shake at the halfway point will work, so what I’d recommend is plan to check it and turn it halfway through the shorter time range that I suggest, and then, to check it again for doneness, at the end of the shorter time range. This way, if you grill doesn’t run as hot, and you can see that you need more time, it’s easy to leave the second side on for a few more minutes.
