Melted chocolate is too thick
Usually over-crystallisation or the wrong material — and the one thing not to do is add water.
Chocolate that is too thick to coat or pour has one of three causes, and distinguishing them matters because the fixes are different.
Over-crystallisation during tempering is the most common: the chocolate has cooled slightly too far and formed too many crystals, thickening it. Warming a degree or two while stirring usually loosens it.
Second, it may not be couverture. An eating bar is simply more viscous when melted, and there is no technique fix — only added cocoa butter.
Third, it may have begun to seize, in which case it will also be grainy rather than merely thick. Adding water to a thick chocolate is the mistake that turns problem two into problem three.
- What it is for
- To thin melted chocolate without ruining it.
- Working temperature
- 29–34°C
- Works with
- Couverture, Cocoa butter
Method
1. Check whether it is grainy as well as thick. Grainy means seizing, which is a different problem.
2. If smooth, warm by a degree or two while stirring. Over-crystallised chocolate loosens readily.
Where people go wrong: Overheating in the attempt, which takes the chocolate out of temper entirely and requires a full restart.
3. If it remains too thick, add melted cocoa butter a little at a time — never water, milk or cream.
Where people go wrong: Adding any water-based liquid, which seizes the chocolate and converts a fixable problem into an unfixable one.
When it goes wrong
| Symptom | Cause | Fix |
|---|---|---|
| Thick but smooth | Over-crystallisation, or an eating bar rather than couverture. | Warm slightly while stirring. If that does not work, add melted cocoa butter. |
| Thick and grainy | Seizing from water contact. | Add substantially more liquid and repurpose as a sauce. It will not return to melted chocolate. |
| Thickens progressively during a long run | Continuing crystallisation as the chocolate sits at working temperature. | Warm gently and stir. Over a very long session a full remelt and re-temper is sometimes needed. |
