Making truffles
Set ganache, shaped and coated. The ratio determines whether it can be rolled, and the ratio changes with the chocolate.
A truffle is a firm ganache rolled or cut and then coated — dusted in cocoa for the classic version, or enrobed in tempered chocolate for a shell.
Everything depends on the ganache setting firm enough to shape, and that is a ratio question rather than a chilling one. Roughly two parts chocolate to one part cream for dark, three to one for milk, four to one for white. A milk chocolate ganache made at the dark ratio will not firm up however long it is refrigerated, which is the most common truffle failure and reads as a technique problem.
- What it is for
- To produce a firm ganache centre, shape it and coat it.
- Working temperature
- 4–20°C — The ganache is chilled to shape and then brought back towards room temperature before coating, so the coating does not crack.

- Chocolate truffle, Dark chocolate, Couverture
Ratios
| For | Ratio | Note |
|---|---|---|
| Dark truffle centre | 2:1 chocolate to double cream | The standard. Sets firm enough to roll once chilled. |
| Milk truffle centre | 3:1 chocolate to double cream | More chocolate for the same firmness, because milk chocolate carries less cocoa solid. |
| White truffle centre | 4:1 chocolate to double cream | The highest ratio of the three and the least forgiving of overheating. |
Method
1. Make a firm ganache at the correct ratio for the chocolate type.
Where people go wrong: Using the dark ratio with milk or white chocolate, which never sets firm enough to roll.
2. Cool to room temperature, then chill until firm enough to scoop.
3. Scoop, roll quickly between cool hands, and return to the fridge before coating.
Where people go wrong: Rolling slowly with warm hands, which melts the surface and leaves a smeared finish.
4. Dust in cocoa, or enrobe in tempered chocolate and set at cool room temperature.
When it goes wrong
| Symptom | Cause | Fix |
|---|---|---|
| Ganache will not firm up enough to roll | Too much cream for the chocolate type — usually the dark ratio used with milk or white. | Melt in more chocolate of the same type. Refrigeration alone will not fix a ratio problem. |
| Coating cracks off the truffle | The centre was too cold when it was enrobed. | Let chilled centres sit for ten minutes before coating. |
