Tried to mix things up again with another unusual dish. We never eat seafood, so I got some shrimp at the store and made some garlic shrimp (camarones al mojo de ajo), which are really simple and tasty.
General recipe (as always, I have no clue how much of anything goes into my dishes):
Melt butter over low heat, add a lot of garlic.
Increase heat to medium-low, add finely diced onion, stir, and cook until the onion starts turning color.
Add shrimp, stir until coated, cook ~3 min.
Add lemon juice, salt, pepper, chili powder, and stir.
Increase heat to medium.
Every minute or so, stir, for ~5 min as the sauce reduces.
Remove the shrimp promptly.
Serve with refried beans, toasted corn tortillas, and/or lettuce.
