Expiration & Storage Tips
When does yellow cornmeal expire?
In general, packaged yellow cornmeal has a best-by date which is usually around a year to eighteen months from the production date. Stored in a cool, dark place, it should retain its quality for the time mentioned on the package, but it doesn't suddenly go bad after this time. Often, it can retain quality for another six to twelve months past this date. Once opened, the cornmeal should stay fresh for up to four to six months when kept in a cupboard or pantry. For extended storage of up to two years, you might want to freeze your cornmeal. Homemade yellow cornmeal, freshly ground at home, has a much shorter shelf-life, typically around a month or two if stored in a cool, dark place and tightly sealed.
How do you tell if yellow cornmeal is bad?
Cornmeal tends to dry out over time, causing changes in texture and becoming less effective in cooking. If you notice unusual color changes, a strong foul or off odor, or if you see mold, it's best to discard your yellow cornmeal. It's always safe to trust your senses – if the cornmeal smells odd or feels too moist, discard it and replace with a fresh pack.
Tips for storing yellow cornmeal to extend shelf life
• Always store cornmeal in a cool, dark place such as a pantry or cupboard. The key enemies of cornmeal are heat, light, and moisture, which can cause it to spoil faster.
• After opening the package, transfer the cornmeal to an airtight container. This will prevent moisture and pests from getting in, prolonging its shelf life.
• Label your container with the date of opening. This will help you keep track of its freshness and prompt you to use it within the best time frame.
• In hot or humid climates, consider storing cornmeal in the refrigerator to keep it fresh for longer. Storing cornmeal in the freezer can extend its shelf life to up to two years.
