  2. Boil the parsnips in just enough water to cover them until thoroughly cooked.

Season and finish

  1. Drain the water, then add a piece of butter, pepper, and coarse sea salt.

  2. Beat the egg with the milk, pour it over the parsnips, and serve hot.

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

What each ingredient does

Parsnips
Provide the bulk of the dish and, once cooked soft, a naturally sweet, starchy body.
Butter
Adds fat that gives a richer, smoother mouthfeel to the cooked parsnips.
Egg
Binds the mixture and thickens it gently as it warms over the parsnips.
Milk
Adds moisture and creaminess, loosening the parsnips into a smooth, pourable cream.

The step that matters

Boil the parsnips until thoroughly cooked. Parsnips that are not fully tender stay fibrous and grainy, so they will not blend or mash into a smooth cream. Cooking them soft lets their starch break down so the texture turns silky.

Swap the parsnip

How well each one fits the dish's main ingredients (butter, pepper, egg, milk):

  1. Capsicumfits better
  2. Potatofits better
  3. Asparagusfits better
  4. Parsnipthe original

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