Step Six: Finish and Serve
If the sauce seems runny, ladle out a bunch and boil it in a separate pot until it's thicker, then add it back in. Master move: Add soy sauce, pepper, brown sugar, or more pimentón to your liking. Maybe a splash of vinegar. Experiment until the flavor really pops. Ladle into bowls, and top with the radishes and chopped celery. Serve with bread and a salad, and congratulate yourself: You just became a better cook.
