The "Pata Negra" induction paellas are specially designed for induction use, although they can be used with all types of fires. They have a flat base and thicker which facilitates heat transmission and makes them more resistant to deformation. Maintenance instructions: As it is a product made of steel to keep the paella in perfect condition, remember that once clean and dry it is necessary to spread it with a paper impregnated with cooking oil. We recommend that you keep it wrapped in paper, inside a plastic bag.
