Called Zilla Eggs, they are about a third of the size of regular avocados and weigh around 70g compared with the average avocado weight of around 200g.
Launched last Friday (August 18), the fruit is being sold by the supermarket chain in recyclable egg-style boxes of six for £2 in 100 branches until stocks run out.
Tesco avocado buyer James Cantoni commented: “These Zilla Eggs are a brilliant way to offer customers great tasting, high quality avocados, which previously would have been rejected by growers because of their size.
“They are perfect for customers who want to snack, without the usual fuss or worry of wasting the other half of the avocado. And it also helps producers who are able to sell even more of their crop.”
The grocery multiple added: “Avocados are the fruit sensation that’s graced millions of Instagram feeds, with demand soaring by more than 30% last year.”
Tesco hopes that its trial of Zilla Eggs will help widen the fruit’s appeal further.
