corn salad with chile and lime

Combine red onion, red wine vinegar, 2 tablespoons cold water, salt, and sugar in a bowl or jar. Set in fridge until needed. Onions will be very lightly pickled by the time you’re done assembling the salad, but if you can give it 1 to 2 hours in the fridge, they’ll be moreso.Heat a grill to medium-high. Lightly oil grill grates and place corn cobs directly on them. Cook corn until charred in spots all over, turning as often as needed. Transfer them to a cutting board to cool slightly. Don’t have a grill? I have often charred corn directly over the gas flame on my stove (be careful; it will crackle and spatter a little). You oven’s broiler, should it be more robust than mine, might also work for the task.While you’re grilling your corn, combine sour cream, mayo, and cotija cheese. Spread on the bottom of your serving plate. Cut corn corn from cobs with a sharp knife and heap it over the cheese spread on the platter. Squeeze the juice of half a lime all over, then scatter the corn with pickled onion rings from the fridge. Generously shake Tajín or chile powder all over; if you’re using plain chile powder, season with salt and an extra squeeze of lime, too. Top with cilantro leaves. Cut remaining lime half into wedges and serve alongside. Eat right away — while the dressing is cold and the corn is hot.
