Chocolate will not set
Three causes, and two of them are materials problems rather than technique ones.
Chocolate that stays soft, marks with fingerprints and never develops a snap is reporting one of three things.
Most often it is out of temper: the cocoa butter has set in unstable crystal forms that are softer and lower-melting than form V. Second, it may not be couverture — an eating bar carries less cocoa butter and genuinely sets softer, and no technique compensates. Third, something has been added that interferes: butter, oil, cream or a water-based flavouring all soften the set, and a ganache is not supposed to set hard at all.
Working through those three in order identifies the cause in almost every case.
- What it is for
- To diagnose why a batch has not set and to determine whether it is recoverable.
- Working temperature
- 29–32°C
- Works with
- Couverture, Dark couverture
Method
1. Check what was added. Any butter, oil, cream or water-based flavouring means the chocolate was never going to set hard.
2. Check the material. If it was an eating bar rather than couverture, a softer set is expected.
3. If neither applies, the temper failed. Remelt fully to 45–50°C, destroying all crystal structure, and temper again.
Where people go wrong: Re-tempering without a full remelt, which leaves the unstable crystals in place and reproduces the problem.
When it goes wrong
| Symptom | Cause | Fix |
|---|---|---|
| Sets soft and fingerprints easily | Out of temper, or not couverture. | Remelt fully and re-temper with tempered seed. If it still sets soft, the material is the problem. |
| Never sets at all, stays fluid | Added fat or liquid. Oil and butter both prevent cocoa butter crystallising into a firm network. | Not fixable as a setting chocolate. Use as a sauce or a soft filling. |
| Sets only in the fridge and softens at room temperature | Out of temper — the unstable forms melt below room temperature. | Remelt and re-temper. Refrigerating to force a set will produce bloom. |
