In Mexico, vendors sell this messy, cheesy, utterly delicious grilled corn from carts. To bring this street food to the home kitchen, we broiled the corn on the cob instead of heading out to the grill, first brushing it with oil to keep it from drying out.
Mayonnaise makes a good substitute for Mexican crema, especially when it’s dressed up with cilantro, garlic, lime, and chili powder.
Hard-to-find traditional Cotija cheese is great, but salty, crumbly feta is just as good. To keep it from crumbling right off the corn, we mixed it in with the mayonnaise before slathering the mixture all over the charred corn and broiling it for another few minutes.
