Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Parsnips
- Provide the main vegetable body and sweet, starchy flavour that the sauce coats.
- Milk
- Cooks the parsnips gently to tenderness while adding a mild, creamy richness.
- Flour
- Thickens the white sauce so it clings to the parsnips instead of running off.
- Butter
- Adds fat and rich flavour to the white sauce and helps form its base.
- Cream
- Adds richness and smoothness to the sauce, giving it a softer, silkier texture.
The step that matters
Boil in milk until quite tender. Parsnips must be fully softened before saucing, because they will not become tender in the short simmer that follows and would stay fibrous.
Swap the mace
How well each one fits the dish's main ingredients (parsnip, milk, flour, butter, cream):
- Nutmegfits better
- Cinnamonfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against parsnip, milk, flour, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
