"But ensure that you are storing your properly, the last thing you want is to get ill from consuming something that has gone off.

"Refrigerating also allows you to get more for your money, as it gives you more time to finish the sauce before binning."

Olivia Lennon, at Heinz Tomato Ketchup said: "There was only ever one correct answer, and we're happy to share with Heinz Tomato Ketchup lovers across the UK that our ketchup has to be in the fridge.

"Although we're aware many fans have been storing their ketchup in the cupboard, we do recommend refrigeration after opening.

"This is the best way to maintain the delicious tangy taste of our Heinz Tomato Ketchup that you know and love."
