Sofrito, also called Recaíto; is a staple to seasoning many Puerto Rican food dishes.
Start off by roughly chopping the yellow onion. Continue doing the same and removing the seeds from the red bell pepper, green bell pepper, and the ají dulces.
Break apart the garlic head into cloves and peel away the outer papery skin. Place the garlic cloves and culantro leaves into the food processor or blender.
Add a tbsp of salt, black pepper, and oregano. Lastly, add the 1/3 cup of olive oil and blend everything together.
