Mojo Criollo is a staple in all Cuban households. It can be used for a variety of different things including to marinade your pork roast or used as a dipping sauce for your plantains or yuca. The strong garlic mixed with the sour citrus is a powerful and delicious combination.
This is another influence we can trace back to the Arabs into Spain. They brought the flavors of the Sour Orange with them. When Spain colonized Cuba, they brought with them that flavor. Once in Cuba, the Garlic was added.
Give it a try! You will not be disappointed.
