The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Enriches the parsnips with fat and carries flavour, and forms the base of the sauce.
Parsnips
Provide the main body and sweet, earthy flavour of the dish.
Flour
Thickens the butter and cream into a smooth sauce that clings to the parsnips.
Cream
Thins the flour-butter base into a rich, pourable sauce.

The step that matters

Boil the sauce once. Flour thickens cream only when heated enough for its starch to swell. Boiling once thickens the sauce fully, while boiling longer can break the emulsion and make it grainy or thin.

Swap the parsnip

How well each one fits the dish's main ingredients (butter, flour, cream):

  1. Leekfits better
  2. Arrowrootfits better
  3. Chivefits better
  4. Parsnipthe original

Fit is the average pairing score against butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
