Supermarket to start selling stoneless avocados with edible skin

A British supermarket is now selling stone-free avocados with edible skin.

The so-called "cocktail avocado" is 5cm-8cm in length and has a smooth, edible skin, meaning it can be sliced or eaten whole and is being sold at Marks and Spencer.

The up-market grocer said there are limited supplies and are being sold during December for £2 ($AU 3.59) for a packet of five.

Earlier this year, the British Association of Plastic, Reconstructive and Aesthetic Surgeons highlighted the increasing numbers of people cutting their hands and fingers while trying to remove avocado stones, and called for safety labels to be put on the fruit, The Guardian reports.

According to The Independent, the stone-free avos are formed by an unpollinated avocado blossom, and not genetically modified.

This process makes them small and elongated.

The flesh is much like a normal avocado - smooth and creamy, pale in colour and rich in flavour, the supermarket claims.

The avocados are grown in Spain.

Charlotte Curtis, a food technology specialist at M&S, said: “We’ve had the mini, the giant, ready-sliced and we’re now launching the holy grail of avocados – stoneless."

"This amazing fruit has been on our radar for a couple of years and we’re very excited to have finally been able to get hold of some for our customers to try.”
