Step 1

Pour 4 cups water into a small pot and bring to a boil over high heat.

Step 2

While water is coming to a boil, remove and discard the stems from the peppers. Transfer peppers to a bowl.

Step 3

Carefully pour boiling water into the bowl. Stir the peppers with a spoon to make sure they're all saturated with water.

Step 4

Cover the bowl with a large plate, aluminum foil or plastic wrap. Let the peppers soak for 15 minutes until softened.

Step 5

Uncover the bowl and transfer the softened peppers to a blender using a slotted spoon to drain out any water.

Step 6

Add tomatoes, garlic, salt and 3/4 cup of fresh water. Puree until completely smooth.
