What each ingredient does
- Rich cream
- Provides fat and body, giving the drink a smooth, rich mouthfeel.
- Vanilla
- Adds aroma and flavor.
- Tartaric acid
- Adds sharp acidity that balances the sweetness.
- Baking soda
- Reacts with the acid to release carbon dioxide, creating fizz.
- Syrup
- Adds sweetness.
The step that matters
Bring the mixture slowly to a boil. Cream scorches on the bottom of a pan and can boil over quickly when heated hard. Heating gently and watching it closely keeps the cream smooth and prevents a burnt taste.
