Chocolate ice cream
Needs more chocolate than seems reasonable, because cold suppresses aroma — and the fat makes it set harder than a vanilla base.
Chocolate ice cream has two problems a vanilla base does not. Cold substantially suppresses aroma perception, so a mixture that tastes strongly of chocolate warm tastes mild frozen, and the recipe needs noticeably more chocolate than intuition suggests.
And cocoa butter is solid at freezer temperature, so a chocolate base freezes harder than a plain custard. Reducing the cream slightly, or adding a spoonful of alcohol or invert sugar, keeps it scoopable.
Cocoa powder alongside melted chocolate gives more flavour per unit of added fat than chocolate alone, which is the usual way round both problems at once.
- What it is for
- To make a chocolate ice cream that tastes of chocolate when frozen and stays scoopable.
- Working temperature
- -18–4°C — Freezing and serving. Letting it soften for a few minutes before serving recovers much of the aroma that freezing suppressed.
- Works with
- Dark chocolate, Cocoa powder, Dutch-process cocoa
Method
1. Build the base with both cocoa powder and melted chocolate rather than chocolate alone.
Where people go wrong: Using chocolate only, which adds a great deal of fat for a modest flavour gain and freezes hard.
2. Taste the base warm and make it stronger than seems right.
Where people go wrong: Seasoning to taste at room temperature. It will taste mild once frozen.
3. Chill thoroughly before churning, and rest the churned ice cream before serving.
When it goes wrong
| Symptom | Cause | Fix |
|---|---|---|
| Tastes mild despite plenty of chocolate | Cold suppresses aroma perception. | Increase the cocoa powder rather than the chocolate, and serve slightly softened. |
| Freezes rock hard | Cocoa butter is solid at freezer temperature. | Reduce the chocolate slightly and add a spoonful of alcohol or invert sugar. |
