The secret ingredient used in many Puerto Rican and Caribbean dishes. Sofrito stores well in the refrigerator or freezer, so make up a batch and have it ready to use when making dishes like Empanadas, Picadillo and other savory Latin American dishes.
Rinse the peppers, culantro and cilantro under cold water. Dry with a towel to remove excess water. Remove stems and seeds from the peppers. Remove the ends from the culantro and cilantro. Peel your onion and garlic.
Roughly chop each ingredient and toss together in a large bowl. Depending on the size of your food processor you may need to make in batches, so have a second bowl ready to pour the sofrito in to.
In the Food Processor
In the bowl of a food processor, place enough of the chopped ingredients until you reach the fill line. Replace the lid and pulse 3-4 times. Scrape down the sides with a spatula and continue pulsing until the ingredients are finely chopped, similar to a chunky salsa.
Pour the sofrito into the clean bowl and repeat the process for the remaining ingredients. Once all the batches are done, mix the sofrito together getting it ready for storage.
To store the Sofrito, pour into mason jars and place in the refrigerator or freeze using either plastic bags or ice cube trays.
