Put hot red chili peppers, Korean hot
pepper sauce, fermented black beans, garlic cloves and ginger into a
blender and blend until a smooth paste is obtained. Heat the
sesame oil until hot and stir-fry the paste over medium heat until
fragrant and oil paste separates from oil, about 10 minutes. Add
hot pepper oil. Set aside to cool and use or keep in an
air-tight container for future use.
