The fresher sweet corn is, the juicier and sweeter it tastes. This means that whether you pick it yourself or you buy it at the market, you should bring it home and eat it as soon as possible. If you must store corn on the cob in the refrigerator, follow specific instructions to keep it as fresh, sweet and juicy as possible. With proper handling, you may preserve corn on the cob in the refrigerator for up to three weeks.
