- 6 fresh tomatillos, husks discarded and tomatillos rinsed
- 1 white onion, quartered
- 2 cloves garlic
- 2 jalapeno peppers, seeded if desired
- 1 1/2 cups water, or amount to cover
- salt to taste
- 1/4 cup chopped fresh cilantro
- 1 tablespoon fresh lime juice, or to taste
- 3 ripe avocados, halved lengthwise and pitted
- Place tomatillos, onion, garlic, and jalapeno peppers into a saucepan over medium heat, and pour in enough water to cover. Bring the mixture to a boil, reduce heat, and simmer until the tomatillos soften and change color from bright green to a yellow-green color, 5 to 8 minutes.
- With a slotted spoon, transfer vegetables to a blender, filling the pitcher no more than halfway full. Hold down the lid of the blender with a folded kitchen towel, and carefully start the blender, using a few quick pulses to get the tomatillo mixture moving before leaving it on to puree. Puree until smooth, about 1 minute; mix in salt, cilantro, and lime juice. Blend again for a few seconds just to mix.
- Scoop out the avocado flesh, and place into the blender; blend until well mixed. Adjust salt, cilantro, and lime juice before serving.
