There’s an ongoing feud about where tomato sauce should be stored. Should it be kept in the cupboard or the fridge? It’s a debate that no one can seem to agree on. But now a definitive answer has been given by Heinz.

This comes after a study of 2,000 people discovered that four in 10 of Brits have been storing their tomato sauce in the cupboard rather than the fridge. But according to Heinz, it turns out that the 41% are wrong, and you’re actually supposed to store it in the fridge.

Many people pointed out that tomato sauce is kept on the shelf at the supermarket. But tomato sauce has natural acidity, which means it’s shelf-stable. When it is opened storage conditions can negatively affect the product, meaning it’s best to keep it in the fridge.
