How to Make It
In a large bowl, mix the water with the sugar and 1/4 cup of salt. Add the corn and let soak for 2 hours or overnight, turning occasionally.
Light a grill. Drain the corn and grill over high heat until lightly browned in spots and tender, 6 to 8 minutes.
Transfer the corn to a large bowl and squeeze the lime all over. Add the cheese, scallions, fresh chile and chile powder and toss until evenly coated. Season with salt and pepper and toss again. Transfer the corn to a platter, scrape any cheese mixture on top and serve.
Cotija is a salty and pungent aged cheese from Mexico that is sold in small rounds and used for grating.
