Toffee Crumble (aka Nibbles/Nibs) - £1.93Price on 28-Oct-09 from A Quarter Of....Toffee Crumble (aka Nibbles or Nibs) - delicious toffee, biscuit, nut and chocolate crumbly bits. It`s one of those sweets where the look of the sweet really doesn`t do the taste justice! It might look a bit like rabbit food - but it certainly doesn`t taste like it. Mind you, I`ve never eaten rabbit food so I wouldn`t know for sure - but if rabbit food tastes like Toffee Crumble then I definitely want to come back as a rabbit in a future life! Whatever the appearance - Toffee Crumble is one of the most moreish sweets that we have.
