The term 'Go Bad, in a Way' can be described by three crossword solutions: ROT (3 letters), MOLD (4 letters), and CURDLE (6 letters). ROT is a process of decomposition caused by bacteria, fungi, or other microorganisms. MOLD is a type of fungus that grows on organic matter and can cause food to spoil. CURDLE is a process in which proteins in a liquid coagulate, causing it to become thick and lumpy. All three processes are ways in which food can go bad, in a way.
