The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: ethanol (alcoholic, ethereal).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barberries
- Provide the main tart fruit flavour, acidity and the red colour of the ice.
- Thick syrup
- Adds sweetness and lowers the freezing point, keeping the ice softer and less icy.
- Vanilla extract
- Adds a light aromatic background that rounds out the tart fruit flavour.
The step that matters
Incorporating the mixture after the first freeze. Stirring the mixture once it is partly frozen breaks up the forming ice crystals. If it is left to freeze solid undisturbed, the ice becomes coarse and grainy instead of smooth.
