Cuban Frita

Steps

1. 1First things first, let's make the dipping sauce by adding the ketchup and mayonnaise in a bowl and mixing well. Set aside.
2. 2Now it's time for the Frita. In a large bowl combine the ground beef and fresh chorizo out of the casing. Then we are going to season with salt, pepper, paprika, and tablespoon of ketchup. Finally we will add the grated onion. Mix everything in gently so everything is well combined and homogeneous, but don't over mix because you don't want the meat to become tough.
3. 3Make 6 to 8 balls from the mixture, then smash them gently. They should be very thin.
4. 4In a griddle or nonstick pan, heat to medium low heat. You don't need oil because the burger will be fatty enough. Place patties on the griddle and cook for 3 minutes on one side and then flip. Cook for another two minutes.
5. 5While the Fritas are cooking, it's time to make the shoe string potatoes and the sauce. Start by heating 1 to 2 cups of oil in a frying pan to medium heat. Fry the potatoes in batches until they are golden brown. Drain them on paper towel and salt them. Set them aside
6. 6In a small bowl add the mayo and ketchup and mix.
7. 7Let's Build the Frita: Place the frita on the bun, top with sauce, lettuce and the potatoes. Press and serve.
