Remember that time #thedress caused rifts in families, turned friends against each other and generally broke the internet?
Now Asda has done it again, causing a condiment conundrum by asking one simple question: do you keep your ketchup in the fridge?
Yesterday the supermarket said one of its stores had begun experimenting with storing ketchup in both aisles and the fridge.
Where do you keep your tomato ketchup? Our colleagues at Asda Clapham have joined the debate by stocking them on shelves AND in the fridge.

The experiment at Asda's Clapham store came after a battle raged on Twitter for months about where people keep their sauce.
Don't trust anyone who keeps their ketchup in the cupboard

Ketchup will survive if you don't refrigerate (room temp-cool temp) it but for quality sake, you should keep it in the fridge after opening.

Peter Barratt, a microbiologist at Initial Hygiene, told the Daily Mail as ketchup now contains less salt, which acts as a preservative, it should be refrigerated once it has been exposed to air.
"No one kept tomato ketchup in the fridge a decade ago, but then it contained more salt," he said.
"In recent years, food manufacturers have had to cut the amount of salt, a natural preservative, because of its links to high blood pressure."
This isn't the first time ketchup has been slathered in controversy: in 2015 techies at Heinz were left red-faced after it emerged a QR code printed on one of its German sauces linked directly to a porn site.
Still – we'll leave the final word on this particular controversy to the condiment's label:
After opening refrigerate and eat within eight weeks.
