Signs of Spoilage
- •Mold growth on the surface or inside the container
- •Unusual darkening or discoloration beyond normal oxidation
- •Separation that doesn't remix with stirring
- •Fermentation bubbles or gas when opening
- •Sour or off smell different from mustard's normal pungent aroma
- •Dried out or excessively hardened texture
- •Noticeably altered or unpleasant taste
Storage & Reheating Tips
- •Store mustard with the cap tightly closed to prevent drying out
- •Always use clean utensils when scooping mustard to prevent contamination
- •Refrigeration isn't necessary for food safety but helps maintain flavor and color
- •Yellow mustard lasts longer than Dijon or whole grain varieties due to higher acidity
- •Homemade mustard has a shorter shelf life (2-3 months refrigerated) than commercial versions
- •If mustard dries out, you can revive it by stirring in a small amount of vinegar or water
- •Store bottles upside down or on their side to minimize air exposure
- •Consider transferring to smaller containers as you use it to reduce air contact
Food Safety Reminder
When in doubt, throw it out! Food can harbor harmful bacteria without visible signs of spoilage.
