Closest of the Slices range to the real thing; if you like lemon slice you'll love it, but it's a 6
Dream white chocolate with lemon flavoured pieces, shortcake biscuit pieces and coconut. Russ says it tastes most like the actual slice of the Cadbury Slices range: the white choc reads as the icing, the biscuit as the base, and it is heavy on the coconut, but there is no lemon twang. The 6/10 is given to lemon slice itself and applied to the bar by implication.

You got no twang, I like a lemon meringue twang baby
