Tomato sauce maker Heinz sparked a debate last month when it urged people to store ketchup in the fridge rather than the cupboard. It issued a tweet decreeing that the condiment should be chilled instead of kept at room temperature, following this up with a survey in which 62% of British voters agreed.
And ketchup isn't alone in being the source of disagreement around where it should be stored. Most condiments can be placed in the cupboard after they're bought and before they're opened - but opinions start to differ once the cap or lid is removed for the first time.
Online supermarket Britsuperstore has now shared its tips on which condiments should really be kept in the fridge and what can be left out. Read on below to find out more.
Condiments to keep in the fridge
- Mayonnaise: Store opened mayonnaise in the fridge to prevent spoilage and it should keep for up to two to three months
- Mustard: Most types of mustard, including Dijon, yellow, and spicy varieties, should be refrigerated after opening to maintain their quality and once opened, can generally be stored for about one to two years. Mustard has a relatively long shelf life due to its high acidity and preservative properties. However, the quality and flavour of the mustard may deteriorate over time.
- Ketchup: Although ketchup contains preservatives, it's recommended to keep it in the fridge for about one to six months. The exact shelf life can vary depending on factors such as the brand, ingredients, and storage conditions
- Barbecue sauce: Most barbecue sauces contain ingredients that can spoil if left at room temperature, so it's advisable to store them in the fridge for about four to six months. However, the exact shelf life can vary depending on various factors such as the brand, ingredients, and storage conditions. It's important to check the expiration date or "best by" date on the barbecue sauce bottle as a guideline.
- Salad dressings: Creamy dressings like ranch, blue cheese, and Caesar should be refrigerated. However, oil-based dressings may be stored in the cupboard. And the shelf life of opened salad dressing can vary depending on the specific type of dressing, ingredients used, and storage conditions.
Condiments that can be stored in the cupboard
- Vinegar: Vinegar, including balsamic, rice, or apple cider vinegar, can be stored at room temperature without any issues. Vinegar, particularly distilled white vinegar, has an almost indefinite shelf life when properly stored, even after opening. Vinegar is highly acidic, which inhibits the growth of bacteria and other microorganisms.
- Soy sauce: Soy sauce has a high salt content, which acts as a natural preservative. It can typically be stored in the cupboard even after opening.
- Hot sauce: Most hot sauces have a high acidity and heat level, which helps prevent spoilage. It's generally safe to store them in the cupboard. Once opened, hot sauce can generally be kept for 1 to 2 years or even longer, depending on the specific brand and ingredients.
- Honey: Honey has natural preservatives and antimicrobial properties. It can be stored in the cupboard, where it will remain in good condition.
- Dry spices: Spices like salt, pepper, paprika, and others in their dry form are best stored in a cool, dry place, such as a cupboard or pantry.
Britsuperstore says: "These guidelines may vary based on individual product recommendations and environmental factors. Always check the specific instructions or recommendations on the condiment packaging for the best storage practices."
