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

How well each one fits the dish's main ingredients (turnip, leek, butter, ham, milk, bread):
