Can You Add Flavoring to Honeycomb Candy?

Yes — you can flavour honeycomb candy, but add heat-stable or concentrated flavourings such as salt, vanilla, malt, coffee, or ground spices at the very end with the baking soda, since delicate flavours can cook or burn off in the hot syrup.

What it means

  • Because the syrup reaches around 150C, robust flavours like vanilla, malt, espresso, cinnamon, or ginger hold up best.
  • Salt is the most popular addition, sharpening the caramel and cutting the sweetness.
  • Adding extracts or powders when you whisk in the baking soda lets them disperse without long exposure to high heat.

Action steps

  1. Choose heat-stable flavours: sea salt, vanilla, instant coffee, malt, or ground spices.
  2. Add them together with the baking soda at the end and whisk briefly.
  3. Pour immediately so the foam sets before the flavour can cook off.

Risks & deadlines

  • Delicate extracts can scorch or evaporate at hard-crack temperatures, so add them last.
