4. If the paste you are using is soft and dries slowly, add CMC powder
(tylo powder/tylose powder) to it.
- CMC makes the paste thicker/firmer and speeds-up the drying time.
- Add it shortly before forming the parts. Knead the paste well.
- If you don't add CMC, the fondant will be soft and the cake topper will sink.
