In a bowl season with lemon juice, salt and pepper the fish fillets, cover it with film transparent or cover and refrigerate for 30 minutes.
In a frying pan over low heat, heat the butter and olive oil. Fry the garlic for a minute and remove before it browns so you don’t know bitter, reserve.
Brown the fish fillets in the same pan together with the remaining butter, two minutes per side.
Serve immediately, top with roasted garlic and Huichol habanero sauce to taste.
Accompany with fresh salad.
