- Chiles de Arbol - about 50 - a good fistful, toasted and then simmered in enough water to cover for 20 minutes or so.
- 2 cloves of garlic - preferably toasted.
- A tablespoon of cider vinegar.
- A tablespoon of sesame seeds - preferably toasted.
- Some onion - not much.
- A couple of cloves
- A teaspoon of salt
Even though the sauce is hot, it does still have flavour. Just remember not to rub your eyes!
