Roasted Tomatillo Salsa Verde

From the blog, A Spicy Perspective, this has been stashed here for safekeeping. I've never grown tomatillos, but may have to now. :)

• Ready In: 35 mins
• Yields: 4 quarts

Ingredients

• 2 1⁄2 lbs  tomatillos, husked and rinsed
• 2  large onions
• 10  garlic cloves
• 4  jalapenos
• 2  tablespoons olive oil
• 4  teaspoons ground cumin
• 2  teaspoons salt
• 1  cup  packed fresh cilantro leaves, chopped
• 3  avocados
• 1  lime (optional)

Directions

1. Preheat the oven to 450 degrees F.
2. Peel and chop the onions into quarters. Place the tomatillos, onions, garlic and jalapenos on a rimmed baking sheet. Drizzle with oil.
3. Roast in the oven for 15 minutes—until the exteriors are blistered but the insides are still slightly raw.
4. Meanwhile, half the avocados, remove the seeds, and scoop out the flesh.
5. Cut the jalapenos in half and scrape out the seeds. Discard seeds.
6. Place HALF of the tomatillos, onions, jalapenos and garlic in a food processor. Pulse until mostly smooth.
7. Add HALF of the cumin, salt, cilantro and avocado. Pulse until the avocado is pureed into the mixture. Taste for salt.
8. Repeat with the remaining ingredients.
9. If you desire an extra tart quality, add a bit of lime juice at the end.
