Waitrose will begin selling "tearless" onions in its stores from next week, which is being billed as a "gamechanger".

As reported by The Guardian, Sunions, which are being marketed using the strapline “not a single tear”, have taken more than 30 years to perfect.

Sunions have been around in the United States since 2018 and they made their way over to mainland Europe last year, with some Spanish retailers stocking them.

They're not exactly cheap though, with a three-pack of Sunions costing £1.50 at 50p per onion.

This is three times as much as Waitrose’s cheapest own-brand onions, which are 14p each.

On the Sunions website it describes the vegetable as becoming sweeter every day, unlike other onions.

It adds: “Volatile compounds in onions are responsible for tearing and pungent flavour and the amounts of those compounds in other onions remain the same or increase over time.

"In Sunions, these compounds do the exact opposite and decrease to create a tearless, sweet and mild onion.”

What hacks are there for cutting onions currently?

Common tactics to avoid tearing up whilst chopping onions have included placing onions in the freezer first, soaking them in water or holding a piece of bread in your mouth whilst you do it.

These strategies may not be needed now if Sunions sell well.
