Coating with chocolate
Getting an even, thin, glossy layer over something. Almost entirely a materials question rather than a technique one.
Coating covers dipping, drizzling and pouring a layer over a cake or a biscuit. What determines success is viscosity: chocolate that flows thinly gives a thin even coat, and chocolate that does not pools and streaks.
That makes couverture close to essential and an eating bar close to hopeless, regardless of technique. The second variable is temperature — chocolate cooling below working range thickens as it crystallises and coats progressively more heavily through a batch.
- What it is for
- To apply an even, thin, glossy chocolate layer to a prepared item.
- Working temperature
- 29–32°C — Working temperature by type. Chocolate cooling below range thickens progressively, which is why later pieces in a batch come out heavier.
- Works with
- Couverture, Dark couverture, Compound chocolate
- Does not work with
- Chocolate chips and eating bars both coat too thickly. This is a materials constraint, not a skill one.
Method
1. Temper couverture and hold it at working temperature in a deep bowl.
Where people go wrong: Using an eating bar, which is too viscous to film thinly whatever the temperature.
2. Bring the item to room temperature and dry it. Work quickly so the chocolate does not drift out of range.
Where people go wrong: Coating chilled items, which cracks the coating as it contracts.
3. Set at cool room temperature rather than in the fridge.
When it goes wrong
| Symptom | Cause | Fix |
|---|---|---|
| Coating is thick and uneven | Chocolate too viscous — either an eating bar, or couverture that has cooled too far. | Warm back into working range, or switch to couverture. |
| Streaks and dull patches | Out of temper, or the item was damp. | Re-temper and dry the item thoroughly. |
What this will not work with
Chocolate chips and eating bars both coat too thickly. This is a materials constraint, not a skill one.
