"Here is my go-to compound which my mami accomplished me while I first began cooking: 3 Roma Tomatos 1 Serrano (or further if you choose it actual spicy) 2 broiled Chile de Arbol (or addition chile of of your choosing) 1/4 onion 2 cloves of garlic Wrap tomato, garlic, onion, and Chile Serrano in foil, and put it over an accessible flame. Flip each two mins for about 5-6 mins until roasted. (You can bake these aforementioned capacity instead for 2 mins on each facet if you prefer).
