Testing the temper
Three minutes and a strip of paper, before you commit a batch. The single most useful habit in chocolate work.
The temper test costs nothing and prevents the commonest expensive mistake there is: moulding fifty pieces before discovering the chocolate was never in temper.
Dip a knife blade or a strip of baking paper, set it aside at cool room temperature and look at it after three to five minutes. Properly tempered chocolate sets in that time with an even gloss, no streaks and a clean snap. Anything still wet, dull, streaky or soft means remelting and starting again — which is annoying at three minutes and ruinous at fifty pieces.
- What it is for
- To confirm the chocolate is in temper before committing a batch to it.
- Working temperature
- 18–22°C — The test room must be cool. Above about 24°C even correctly tempered chocolate will not set in five minutes and the test gives a false negative.
- Works with
- Couverture, Dark couverture
Method
1. Dip a knife tip or a strip of baking paper into the tempered chocolate.
2. Set it aside at cool room temperature — not in the fridge, which sets anything.
Where people go wrong: Testing in the fridge. Cold sets untempered chocolate too, so the test tells you nothing.
3. Check at three to five minutes for even gloss, no streaks, and a firm break. If it fails, remelt and re-temper.
When it goes wrong
| Symptom | Cause | Fix |
|---|---|---|
| Test never sets, but the temperatures were right | The room is too warm, or the chocolate contains added fat. | Test somewhere cooler. If it still fails, check that nothing oily was added. |
