About honeycomb toffee
Honeycomb toffee, also called cinder toffee in Britain, is an aerated sugar confection whose open structure comes from bicarbonate of soda foaming hot caramel. This profile uses the compact British golden-syrup version without a chocolate coating.
Caster sugar supplies a clean caramel sweetness, while golden syrup adds a deeper toasted, slightly buttery note and helps keep the cooked sugar smooth. The bicarbonate contributes no intended flavour beyond a faint mineral edge when properly dispersed.
The set toffee is deep amber and breaks into jagged shards filled with irregular bubbles. It is rigid and glassy at first bite, then collapses into a light, crisp, sponge-like crunch.
