Cilantro-Chili Pepper Sauce

1 . Stage

Cut the stem end off of the chile peppers, and remove the seeds using a thin knife, otherwise leaving the peppers whole. Place the peppers into a skillet, and toast over medium-high heat, turning frequently, until the skins of the peppers have blackened and loosened, about 10 minutes. The peppers are ready when 1/4 of the skin has blackened. Remove the peppers, place into a small bowl, and cover with plastic wrap. Allow to cool and steam for about 15 minutes, then remove and discard the skins. Chop the peppers, and set aside.

2 . Stage

Heat the sesame oil in the skillet over medium heat. Stir in the garlic, and cook for 2 minutes to soften, then increase heat to medium-high, and stir in the chopped peppers and salt. Cook and stir until the mixture is hot and sizzling, about 1 minute. Pour in the vinegar, brown sugar, and fish sauce. Bring to a boil, then reduce heat to medium-low, and allow to simmer for 10 minutes.

3 . Stage

Scrape the mixture into a blender, and add the soy sauce, lime juice, cilantro, and green onion. Puree until smooth. Serve immediately.
