10 ears of corn, shucked
1/2 cup mayonnaise
1/2 teaspoon finely grated lime zest
3 tablespoons fresh lime juice
1/2 teaspoon finely grated lemon zest
1 tablespoon fresh lemon juice
1 tablespoon extra-virgin olive oil, plus more for brushing
1/2 teaspoon Dijon mustard
1 garlic clove, finely grated
1/8 teaspoon cayenne
4 tablespoons unsalted butter, softened
qpproximately 1/2 cup cotija cheese, crumbled (optional)
1/2 cup chopped cilantro
Bring a large pot of water to a boil. Add the corn and a generous pinch of salt and return to a boil. Remove from the heat, cover and let stand for 5 minutes. Drain the corn and let cool slightly.
Meanwhile, in a small bowl, whisk the mayonnaise with the lime and lemon zests and juices along with the 1 tablespoon of olive oil, the mustard, garlic and cayenne. Season the citrus aioli with salt.
Light a grill or preheat a grill pan. Brush the corn with olive oil and season with salt. Grill over high heat, turning occasionally, until lightly charred all over, about 5 minutes. Transfer to a plate and let cool slightly, then cut the kernels off the cobs; discard the cobs.
Step 4 In a large bowl, toss the corn with the softened butter. Stir in the citrus aioli. Add the queso fresco, cotija, parsley and cilantro. Season with salt and pepper and serve warm.
