I first encountered this when I was chronologically little usually in folded over cardboard containers from the frozen food cabinet in our nearest towns store looking for something to have with our Sunday main meal.
Called Neapolitan Ice cream, it has the strawberry, vanilla and chocolate flavours all in one arranged so when you slice it, you get equal portions of each flavour and it went well with jelly!
Just marvellous!
I also had Viennetta for the first time in ages last week with cream and chocolate outer shell and that was delicious.
