Rinse cilantro and let the excess water run off.. Wash and de-seed the chili peppers (Use gloves for this one as the chili can be very spicy). Peel your garlic cloves.
Use a meat grinder to grind all the ingredients together. Mix the walnuts and the garlic together with the cilantro when grinding. This helps the cilantro juices from running out so much.
Pour the oil into a skillet or heavy bottom pan. Bring to smoking point. Pour the hot oil over the ground cilantro walnut mixture. Add salt and mix very well.
Transfer to a jar and store in the fridge. Consume within a week.
