The term 'preserves, as pork' can be solved by the five-letter word 'SALTS'. Salting is a traditional method of preserving food, especially meats such as pork. This method involves rubbing salt into the meat and then storing it in a cool, dry place. The salt draws out moisture from the meat, which prevents the growth of bacteria and other microorganisms that cause spoilage. Salting also adds flavor to the meat, making it more palatable.
