The debate over whether ketchup should be stored in the fridge or cupboard continues to divide opinions. Refrigerator supporters argue that cooling ketchup preserves its flavor and extends its shelf life, citing label instructions from brands like Heinz. In contrast, cupboard advocates point to the use of preservatives like vinegar and sugar, claiming that ketchup remains stable at room temperature, similar to restaurant practices. Heinz recommends refrigeration for optimal taste and freshness, while experts like Dr. Sarah Schenker say refrigeration isn’t necessary. Ultimately, the decision comes down to personal preference, as there’s no definitive right or wrong way to store ketchup—just enjoy it the way you like it best!

What About the Experts?

• Mayonnaise: Always keep in the fridge after opening. Since it contains eggs, it can spoil quickly at room temperature.
• Salad Cream: Like mayo, it’s best stored in the fridge after opening.
• Mustard: Can safely stay in the cupboard, though refrigeration may help it retain its sharpness.
• Brown Sauce: This vinegar-based sauce is stable at room temperature, so it’s fine in the cupboard.
