How to Cure a Copper Caso
A copper caso is a large cooper pot used to cook alkaline foods such as meat, pasta and high-sugar foods. Acidic foods such as fruits, tomatoes, salad dressings and vinegar containing foods should not be cooked in a copper caso due to the toxic chemical reaction between the copper and the acid in the food. Cure a copper caso before the first usage and after each cooking session with a coating of vegetable oil.
Cut a lemon into 1/4-inch slices. Sprinkle baking soda over the slice.
Rub the lemon and baking soda over the cooking surface of the copper caso.
Rinse the copper caso with warm water and dry.
Dip the corner of a cloth in vegetable oil. Rub the cloth over the cooking surface of the copper caso. Store for future use.
