Melted chocolate is too thin
Almost always temperature. Chocolate above working range is fluid because it is out of temper, not because it needs thickening.
Chocolate that runs off a centre and leaves a coating too thin to look right is usually simply too warm. Above working temperature the crystal network has not begun to form, so the chocolate is fluid — and it is also out of temper, which means it will set dull and soft.
The fix is to cool it into working range with tempered seed, not to add anything. Thickening agents do not work in chocolate: it is a fat-continuous system, and starch or sugar added to thicken it will simply sit there as grit.
A genuinely thin couverture — one formulated with very high cocoa butter for enrobing — will always coat thinly, and that is what it is for.
- What it is for
- To bring over-fluid chocolate back to a workable coating consistency.
- Working temperature
- 29–32°C — Fluidity and temper are the same question. Chocolate thin enough to run freely is generally too warm to be in temper.
- Works with
- Couverture, Dark couverture
- Does not work with
- Do not attempt to thicken chocolate with starch, flour or icing sugar. Chocolate is a fat-continuous system and these will not dissolve — they will sit as grit.
Method
1. Check the temperature. Above about 34°C the chocolate is out of temper and will be fluid.
2. Cool it into working range while stirring, adding finely chopped tempered chocolate as seed.
3. If it is at the right temperature and still too thin, the material is a high-fat enrobing couverture and is behaving as designed.
When it goes wrong
| Symptom | Cause | Fix |
|---|---|---|
| Runs straight off the centre | Too warm, and therefore out of temper. | Cool to working temperature with tempered seed while stirring. |
| Correct temperature but still coats thinly | A high-fat enrobing couverture, formulated for exactly this. | Nothing is wrong. Use a lower-fat couverture if a thicker coat is wanted, or apply a second coat. |
What this will not work with
Do not attempt to thicken chocolate with starch, flour or icing sugar. Chocolate is a fat-continuous system and these will not dissolve — they will sit as grit.
