Chop the onions and garlic.

Blanch the onions and garlic to soften them. (Place in hot water for 5 minutes then strain.)

Chop the jalapeños (use fresh or canned not pickled.)

Combine these three ingredients and the cilantro leaves in food processor and blend for a few seconds.

Add remaining ingredients and blend until well mixed but not pureed.

Cover and fill at least two hours before serving.
