Why it works: Arrowroot and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 1,073 recipes. Both carry 1-penten-3-one, which smells fish, pungent. 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 light, glossy body as it heats.
- Fruit juice
- Provides the main flavour and colour of the soup.
- Sugar
- Sweetens the soup and balances the tartness of the fruit.
The step that matters
Boil the arrowroot mixture briefly. Arrowroot thickens when heated and must be stirred into the hot liquid. If it is not heated enough, the soup stays thin. Once it boils and thickens, adding the juice cold or overheating can dull the texture, so it is best to add the juice after the thickened base is ready.
