Why it works: Celery and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 18,518 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Rice Cream Soup
Ingredients
Directions
Prepare
Combine onion and celery in the stock.
Tie the mace, sweet herbs, and peppercorns in a small piece of muslin and add to the stock.
Bring the stock to a boil.
Thicken
Mix rice flour with about 2 cups of milk.
Add the rice flour mixture to the boiling stock.
Stir the mixture until it thickens.
If the soup is too thick, add more milk or stock.
Cook slowly.
Finish
Mix the remaining milk with the egg yolks.
Add the yolk mixture to the soup just before finishing.
Pass some of the vegetables and rice through a sieve.
Carefully stir in the yolks and milk mixture.
Pour the soup into a jug.
Place the jug in a saucepan with boiling water to thicken.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice flour
- Starch swells in the hot liquid and thickens the soup.
- Egg yolks
- Proteins set on gentle heating, adding body and richness to the soup.
- Milk
- Provides the creamy liquid base and dairy richness.
- Stock
- Forms the savoury liquid that the vegetables and rice cook in.
The step that matters
Carefully stir in the yolks and milk mixture. Egg yolk proteins set and can curdle or turn grainy if the soup is too hot when they go in. Adding them gradually and keeping the soup below a boil helps them blend smoothly into the thickened base.
