Marked by the grill, the silver skin of a whole trout looks beautiful on the plate. If you don’t want to grill trout on the bone, it’s easy enough to find boneless butterflied trout at the fish counter. Stuff them, fold them over to look like whole fish, tie them up with twine, and then proceed to the grill. Chowchow is a Southern relish typically made with cabbage, corn, green tomatoes, and bell peppers and preserved in big batches by canning. My version is a sweet, tangy quick pickle of fresh summer corn, charred on the grill, and diced black plums.
