Thanks! It's incredibly easy, though.
The ceviche is just a matter of going to a decent fish market and asking, "So, what marine fish are fresh today? I'd like to make ceviche." Literally anything fresh is fine, but I do like to stick to salt water for stuff I'm making at home.
About 1 lb of fish, some lime juice, some orange juice, some thinly sliced red onion, your favorite chile, and then whatever else you have floating around that sounds good. I think this batch had some avocado, Fresno chiles, and some chives that were getting old. I like to marinate mine for about 15 minutes and cut the fish into larger slices to get a nice contrast in texture between the "cooked" outside and the raw inside. You can marinate for less time for a more sashimi-like experience, or 45 min+ if you like well done steak and chili with beans. If you want to make it look even fancier, you can throw it in a chilled martini or coupe glass and serve it up as an appetizer.

Esquites are just elotes off the cob. Grilled or skillet-charred corn + mayo + chili powder + lime juice+ cilantro + cotija cheese.
