Why it works: Brandy and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 3,738 recipes. Both carry gamma-nonanolactone, which smells coconut, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Thickens the liquid into a jelly-like gel as it heats and simmers.
- Egg
- The frothed white adds lightness, while the yolk is mixed in to help smooth the thickened jelly.
- French brandy
- Adds aroma and flavour to the finished jelly.
The step that matters
Pour the arrowroot mixture slowly into the boiling water while stirring continuously. Arrowroot forms lumps if it meets hot liquid all at once. Adding it slowly while stirring keeps it dispersed so it thickens evenly into a smooth gel.
Swap the arrowroot
How well each one fits the dish's main ingredients (egg, brandy, milk):
- Potatofits better
- Sweet potatofits better
- Asparagusfits about as well
- Arrowrootthe original
Fit is the average pairing score against egg, brandy, milk. Candidates are from the same food group and used in at least 100 recipes.
