Corn Esquites

4 ears sweet corn, husked and silks removed
4 tablespoons mayonnaise or Mexican sour cream
4 tablespoons unsalted butter, softened
6 tablespoons crumbled queso fresco or mild feta cheese
Ground chili powder, for sprinkling
Salt, for sprinkling
Lime wedges, for serving, optional

Bring a large saucepan of salted water to a boil over medium-high heat. Add the corn and cook until tender, about 5 to 7 minutes. Using tongs, transfer the corn to a platter and allow them to cool slightly. Using a serrated knife, remove the kernels from the corn. Divide the corn between 4 individual cups or small glasses. Put 1 tablespoon mayonnaise and 1 tablespoon butter in each glass. Sprinkle with cheese, chili powder, and salt. Serve with the lime wedges, if desired.
