Step 1

Preheat oven to 350 degrees F. Heat oil in a large skillet over high heat until hot but not smoking. Add corn and jalapño and cook, without stirring, until lightly charred, about 3 minutes. Stir and cook for another 3 minutes. Transfer the mixture to a medium bowl. Stir in mayonnaise, crema (or sour cream), lime juice, chili powder and 1/2 cup queso fresco.

Step 2

Spread the mixture in an 8-inch glass pie pan or 1-quart baking dish. Top with the remaining 1/4 cup queso fresco and sprinkle with cayenne. Bake until the cheese is melted and the outer edges begin to bubble, about 12 minutes. Garnish with chopped cilantro and serve with tortilla chips, if desired.
