The corn salad that fills these tacos makes a great side dish as well. If you are averse to raw corn, you can always blanch the kernels in boiling water for one minute before proceeding with the recipe.
Combine corn, cotija, lime zest, lime juice, oil, cayenne, cilantro, and scallions in a bowl. Season with salt.
Toast tortillas individually over a gas burner, or spread in a single layer on a baking sheet and broil, turning once to char both sides. Fill with mango slices and corn salad. Serve with lime wedges for squeezing.
