Frequently Asked Questions

What's the difference between expiration and best quality dates for Dijon Mustard?

Over time, Dijon Mustard may lose its pungency and flavor intensity, but it remains safe to consume beyond the 'best by' date. The texture may become slightly grainy or separated, but stirring can restore its consistency. While quality may degrade, the safety of the mustard is maintained due to its acidic nature.

How can I tell if Dijon Mustard has gone bad?

To determine if Dijon Mustard has gone bad, look for signs of mold growth on the surface, a sour or off smell, or a change in texture such as becoming excessively watery or chunky. If you notice any of these indicators, it is best to discard the mustard to avoid consuming spoiled product.

What are the food safety risks with Dijon Mustard?

Dijon Mustard poses low foodborne illness risks due to its high acidity and antimicrobial properties. However, contamination can occur from cross-contamination with utensils used for raw meats. To prevent illness, always use clean utensils and refrigerate promptly after each use.

What are some pro tips for storing Dijon Mustard?

To maintain optimal flavor and quality, store Dijon Mustard in a cool, dry place away from direct sunlight. Refrigeration can help preserve its freshness, especially after opening. Ensure the cap is tightly sealed to prevent air exposure, which can lead to flavor deterioration. For extended shelf life, consider transferring small amounts to a smaller airtight container to minimize oxidation.
