Sofrito Recipe

Sofrito is the secret ingredient in many Latin Caribbean dishes and it's so easy to make. It's a versatile, aromatic puree of  peppers, cilantro, onions, and garlic. You may use a food processor or blender for desired reults. This recipe makes about 1 quart of sofrito.  (this is the Puerto Rican version)
Ingredients

• 2 medium green peppers, seeds removed
• 1 red sweet pepper, seeds removed
• 2 medium onions, peeled
• 1 head of garlic, peeled
• 1 bunch cilantro leaves

Peel garlic and chop ingredients into sizes that are small enough to fit into a food processor or blender.  Place the chopped ingredients into a food processor or blender.

Tip: If you find it necessary to add liquid, you may add water or oilive oil a tablespoon at a time
Blend together all ingredients well.  For immediate use, store in a glass container. Plastic containers are not ideal because plastic will absorb the odor of garlic and onions.
For future use, freeze sofrito in 1/4 to 1/2 cup portions for use at any time; I put it in ice cube trays and use about 2-3 cubes for recipes.

I use it in taco meat, meat dips, meat balls, meatloaf, eggs, etc.  It's great in just about every dish.
