Olla is a Spanish word meaning 'POT' or 'JAR'. It is also used to refer to a type of stew, known as OLLA podrida, which is a traditional Spanish dish made with a variety of ingredients such as meats, vegetables, and legumes. OLLA podrida is a miscellany of ingredients, hence its name, which literally translates to 'rotten POT'. The stew is usually cooked slowly over a low heat for several hours, allowing the flavors to blend together.
