The best way to store open mustard is in the refrigerator.
Why Refrigerate Mustard?
Refrigerating mustard, regardless of the type (Dijon, yellow, or whole grain), helps to maintain its flavor and quality over a longer period. According to the USDA, refrigerated mustard can last up to a year after opening.
Mustard Storage Best Practices:
- Refrigeration: Always store open mustard in the refrigerator.
- Airtight Container: Ensure the lid is tightly sealed to prevent the mustard from drying out and absorbing other flavors from the fridge.
- Shelf Life: While mustard can last for a year refrigerated, be mindful of changes in taste or appearance, which may indicate spoilage.
- Dried Mustard: Note that dried mustard powder should be stored in the pantry with other spices.
What About Different Types of Mustard?
The recommendation to refrigerate applies to most common types of prepared mustard.
- Yellow Mustard: Benefits significantly from refrigeration to maintain its tang.
- Dijon Mustard: Refrigeration helps preserve the sharpness and distinct flavor.
- Whole Grain Mustard: Keeping it cold helps prevent the seeds from drying out and becoming brittle.
In summary, keep open mustard in the refrigerator for optimal flavor and shelf life.
