Remove the stems and seeds from the anchos, guajillos and chiles de arbol. Chop into very small pieces, about 1/4 inch or smaller. Set them aside.
Add the peanuts, garlic, sesame seeds and oil in a medium pot. Heat to medium-high heat and cook for 5 minutes, or until the garlic starts to crisp up and the seeds turn golden brown.
Remove from heat and stir in the chili pepper bits. Allow to cool for 10 minutes.
Stir in the vinegar, salt and Mexican oregano.
Pour the mixture into a blender or food processor and pulse several times until the salsa is nicely combined. Don’t over-process the salsa macha, as you want to have nice crispy bits, not a puree.
