The Taste of Britain cone features 20 regional flavours
Three Scottish delicacies - the Arbroath smokie, haggis and shortbread - are being turned into ice cream flavours.
Harrods will be offering customers the flavours, along with 17 other regional favourites from across Britain, over the next few days.
The Taste of Britain cone also features Yorkshire pudding, sausage and mash and Worcestershire Sauce.
Black pudding, Cornish pasty and Welsh Rarebit are also on the menu.
The ice cream's creator, master gelatiera Gino Soldan, told the BBC Scotland news website that the Scottish tastes had their challenges.
He said: "The fishy one [the Arbroath smokie] was the most difficult of the three because it was difficult to find the fish - everything is made with the real ingredient. I mixed it with a neutral base of ice cream and the result I think is not bad.
"The shortbread is very easy because the shortbread I made with butter, sugar and egg, so it's one of the easiest flavours."
He also mixed haggis with a neutral base of ice cream, explaining: "I tried to give a quite nice taste because personally I don't like haggis and I think the result is good."
Mr Soldan does not see the ice cream being eaten as a dessert but in a savoury platter or in combination.
He said: "A combination of the fish ice cream with maybe smoked salmon or some dill and cream cheese is quite good."
However, one fish expert in Arbroath was not impressed with the idea.
Councillor Bob Spink, who worked in the family fish merchants for about 55 years, said: "The two are as compatible as kippers and custard so I find the whole idea quite ridiculous.
"I can't imagine there'll ever be queues of people wanting to buy it."
He added that when a local fish and chip shop tried smokie ice cream years ago the idea never caught on, while smokie-flavoured vodka also suffered the same fate.
But Mr Spink does not want to stop people experimenting.
"I don't blame people for trying new ideas," he said.
"It's a bit of fun and it keeps the smokie's profile up."
