Temperature control
Six numbers govern almost everything: three melting ceilings and three working windows. Most chocolate failures are one of them being missed.
Chocolate work is a temperature discipline more than a manual one. The melting ceiling is 50°C for dark and 45°C for milk and white; past it the sugars caramelise and the damage is permanent. The working window is 31–32°C for dark, 30–31°C for milk and 29–30°C for white; outside it the chocolate is either out of temper or too thick to use.
The room matters as much as the bowl. Setting needs an ambient temperature below about 20°C, and below 18°C for milk and white. A correctly tempered batch in a 26°C kitchen still will not set, and no adjustment to the chocolate fixes the room.
This record exists as the reference the other preparation records point at, so the numbers live in one place rather than being restated in each.
- What it is for
- To hold every stage of chocolate work inside the temperature range it requires.
- Working temperature
- 15–50°C — The full span the discipline covers, from setting room to melting ceiling. No single number applies across it — the type and the stage both matter.
- Works with
- Dark chocolate, Milk chocolate, White chocolate
Method
1. Melt below the ceiling for the type: 50°C dark, 45°C milk, 45°C white. Use a probe thermometer rather than judgement.
2. Temper to the working window for the type: 31–32°C dark, 30–31°C milk, 29–30°C white.
Where people go wrong: Using one set of numbers for all three types. The windows are two degrees wide and they do not overlap.
3. Set at 15–18°C in a dry room, not in a fridge.
Where people go wrong: Setting in the fridge, which draws condensation and causes sugar bloom on the surface.
When it goes wrong
| Symptom | Cause | Fix |
|---|---|---|
| Everything is right and it still will not set | The room. Above about 24°C nothing sets properly however good the temper. | Move to a cooler room. This is the constraint people check last and should check first. |
