Londoners basking under Britain’s hottest ever summer are getting the chance to find out what baked bean ice cream tastes like – and a range of other flavours more readily associated with savoury winter dishes, including porridge oats and HP sauce.

At a short-term pop-up promotional store organised by fashion designer Anya Hindmarsh, visitors can try a range of 14 flavours Hindmarsh considers to be “cult” British grocery products. Sold in 500ml tubs for taking home or served by the scoop in-store, the flavours range from salty Kikkoman Soy Sauce and creamy Heinz Mayonnaise through to sweeter flavours like Lyle’s Golden Syrup and Polos. 

The store, at London’s The Village, opened on July 9 and will trade until August 28. Anya Hindmarsh reports it has proven so popular with regular long queues, the label has apologised if not everyone can be served by closing time.

“There’s lots of weird flavours and … me and my sister were very excited to try lots of them,” nine-year-old Izzy Konviser, a customer at the Ice Cream Project, told Reuters.

“I think the weirdest … is probably ketchup, and baked beans because it’s just like the most unusual thing that you would ever have.”

Store employee Hannah Wearne said six weeks supplies sold out in four days. “We’ve been really, really popular… and we’ve got our own regulars which is really lovely,” she said.

• Kikkoman Soy Sauce – Toasted sesame ice cream laced with umami-rich naturally brewed soy sauce.
