Bits & Pieces

The fondant in the centre of After Eights is made as a stiff paste of saccharose, water, and a small amount of the enzyme invertase. This fondant can readily be coated in dark chocolate. After manufacture, the enzyme gradually splits the saccharose into the much more soluble glucose and fructose, resulting in a more liquid consistency.[1] Maturing of the mint is said to take over three months.
