Chilled Tomatillo Avocado Soup
- Preheat the broiler and place an oven rack in the top position. Line a baking sheet with foil. Broil the tomatillos, garlic and jalapeno (if using) on the baking sheet for 5 minutes. Keep an eye on the vegetables while they're broiling to make sure they don't burn. Turn the ingredients over and broil for another 5 minutes. The tomatillos should be brown in spots and will have started releasing juices. Remove from the oven.
- Add the tomatillos, garlic, jalapeno, cucumber, shallot, cilantro, stock, lime juice, salt and water to a blender. Pit the avocado and scoop the flesh into the blender as well. Puree until very smooth.
- Pour the soup into a large bowl, cover, and refrigerate for at least 2 hours before serving to allow to flavors to blend.
