Ketchup 'fridge or cupboard' debate finally settled - and some may be surprised The UK's love for ketchup is undeniable, with the tangy red sauce being a staple in many households for everything from chip dipping to bacon sandwich slathering.
This advice is reiterated in the Instagram post's caption, which reads: "The debate over where to store your ketchup is one that constantly simmers across social media: fridge or cupboard?
The expert does add a note of caution, stating: "If it takes you a while to get through a bottle, you might get a longer shelf life from it if you keep it in the fridge".
There's no need to keep ketchup in the fridge – unless you prefer the taste of it chilled.
But tomatoes are naturally acidic, and the sauce contains vinegar, which helps preserve it in ambient conditions.
