Tesco is trialling avocado ripeness scanners and fans of the fruit are divided over whether it is a shopping hack or if a squeeze test should suffice.
Avocado toast has become synonymous with the millennial generation but it relies on the main ingredient being soft enough for smashing.
Shoppers at five Tesco stores in England can scan their avocados to find out how ripe they are. Tom Allingham, money expert at Save the Student, says it's "only fair" people know what they're paying for.
But James Herring, CEO at brand consultancy Taylor Herring, thinks it's a tech gimmick and giving an avocado "a quick squeeze" works just as well.
"Britain's supermarkets are locked in a never-ending battle for attention and spend, so every day brings a new gimmick," he says.
