High-risk scenarios include leaving mustard at room temperature for extended periods or using expired products.
Expiration vs Best Quality
Over time, the flavor and potency of mustard can degrade due to exposure to air, light, and moisture. While the expiration date indicates safety, the best quality of mustard is typically within the first few months of opening. After expiration, the flavor may diminish, and the texture can become watery or grainy.
