Why it works: Onion and parsley are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Provides the main meat, which becomes tender as the soup simmers.
- Onions
- Soften and sweeten as they cook in butter, building the flavour base of the broth.
- Flour
- Lightly thickens the broth and helps it coat the meat and vegetables.
- Sago
- Thickens the broth as it heats, giving it body.
The step that matters
Bring the broth to a boil and add sago until it thickens. Sago thickens only as its starch swells in hot liquid and can clump if added carelessly. Adding it gradually to a boiling broth, while stirring, helps it disperse evenly and thicken smoothly.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, butter, flour, parsley):
