In the 60s and 70s, having a frozen dessert you could serve at a moment’s notice was the posh thing to do. The simple but glorious arctic roll started popping up everywhere, from restaurants to school and hospital menus. Eventually it became seen as something a bit naff and tacky, but I think smearing a home-made sponge with quality jam, good ice cream and a little bashed-up honeycomb is easy, fun, and just a bit silly. Roll it up, freeze it for a few hours, and you’ll get sweet and sour, crunch and softness, all in one mouthful. Heaven.
