Kitty and Mark travel through time celebrating sweets from the past and creating up-to-the-minute treats with some rather unsweet ingredients.

Kitty and Mark make sweets with medicinal roots, including soothing rose and pistachio turkish delight and salt liquorice caramels.

Kitty and Mark make sweets that are perfect for sharing. These include sticky lemon and blueberry nougat, a fudge bursting with coffee and ginger cake, the simplest pear and ginger coins and an old-fashioned cinder toffee.
