Farmers from Bedfordshire and Cambridgeshire are supplying Tesco with the Supasweet onion that is specially bred - not genetically modified - to halve the content of the ingredient, which irks the eyes and nostrils.
It is also said to be mild enough to eat like an apple. The Supasweet has been developed with government-funded research by British farmers and should be already available at most other supermarkets. Growers at the Lincolnshire-based Allium and Brassica Centre and scientists from the University of Liverpool have also been involved. The new onion has a distinctive pale, thin skin and is easy to peel. It has been grown in low-sulphur soils to cut the pyruvic acid content.
Tesco's fresh produce director, Steve Murrells, said "Since onions form the base of so many of today's dishes, the Supasweet will open up a new world of cooking to them." And added "It heralds the beginning of a new era of food without tears.
"While many of us will have suffered the stinging effect of peeling onions, a minority experience such a severe reaction that they never cook with onions again.
It is said to cost 99p for a 500g pack of two - the same price as two imported Spanish red onions.
