Oh god, cotija cheese is so good. It's a crumbly, hard, mild-tasting Mexican cheese that I first discovered a few years ago, when Francesca took me to a place on the Lower East Side called Cafe Habana that specializes in cotija-covered corn (a.k.a. Mexico City Street Corn), and - despite my insistence that I do not like things that have red things (in this case, chile powder) sprinkled on them because red sprinkly things are often spicy, and another thing I do not like is anything spicy - she force-fed it to me.
And it was a terrible, horrible idea. Because what happened next was that I started making this cotija cheese-covered corn (albeit with paprika subbed in as the obligatory Red Sprinkly Thing, because paprika is not spicy) every freaking time it was humanly possible, including every single night during the summertime. And that is a lot of cheese (and mayonnaise).
