How can you tell if high ratio shortening is rancid if it has no taste?

To determine if high ratio shortening is rancid, you can check for off odors, as rancidity often produces a distinct, unpleasant smell even if the taste is not apparent. Additionally, inspect the texture and appearance for any signs of separation or discoloration. If the shortening has been stored improperly or past its expiration date, it’s best to err on the side of caution and discard it. Always trust your senses—if something seems off, it's safer not to use it.
