In a saucepan, bring water to a boil and add the tomatillos. Cook for about 5-7 minutes until they are soft and their color changes to a dull green.

Remove the tomatillos from the water and let them cool slightly.

In a blender, combine the cooked tomatillos, onion, garlic, jalapeño, cilantro, lime juice, and salt.

Blend until smooth or to your desired consistency.

Taste and adjust seasoning if necessary. Serve immediately or refrigerate for later use.
