Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Provide the bulk of the soup and a mild, slightly sweet vegetable body.
- Leeks
- Add a mild onion-like aroma and soften into the soup's base.
- Celery
- Adds aromatic depth and body as it softens during simmering.
- Milk
- Adds creaminess and a smooth, rich texture to the soup.
- Bread
- Thickens the soup slightly and adds body as it breaks down.
The step that matters
Bring to a boil 2 or 3 times. Milk can scorch or curdle if it sits at a hard boil on the base of the pan. Stir often and keep the heat controlled so the soup stays smooth and creamy rather than grainy or burnt.
Swap the celery
