Sepen

Sepen is an extremely hot and spicy sauce originating from Tibet. Although there are many variations (thick or thin, chunky or smooth), it's usually made with a combination of red hot chili peppers, onions, tomatoes, scallions, garlic, celery, coriander, salt, and oil. The ingredients are chopped by hand and stir-fried in oil until everything is cooked down. Once cooked, the sauce can be enjoyed as it is or mashed and blended until smooth. Sepen is typically served with mild Tibetan foods such as momo dumplings or laping.
