* Cotija cheese can be found in the Mexican section of the grocery store, either pre-grated like Parmesan cheese or is also sold in a block. If you can't find Cotija cheese, Parmesan is a possible substitute.
* The amount of oil needed will depend on the size of your frying vessel. Fill no more than 1/3 full to allow room for expansion of the hot oil. Vegetable, Grape Seed, Corn or Canola oils are all suitable for frying.
