Parsnip with Crbam Saucb

Ingredients

Directions

Prepare the parsnip

  1. Scrape and wash the parsnip without soaking it.

  2. Cover the parsnip with boiling water and cook until tender, about 20 to 30 minutes.

  3. Cut the parsnip into slices half an inch thick.

Make the sauce

  1. In a saucepan, stir together the butter and flour to form a cream.

  2. Add the boiling water to the cream mixture, then season with salt and pepper.

  3. Boil the sauce for 10 minutes.

Finish and serve

  1. If the parsnip has a hard core, cut it out of each slice and discard.

  2. Serve the parsnip slices in a vegetable dish, topped with the sauce.

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

What each ingredient does

Parsnip
Forms the body of the dish and, when cooked until tender, adds natural sweetness.
Butter
Adds fat and richness, and coats the flour so it blends smoothly into the sauce.
Flour
Its starch swells in hot liquid and thickens the sauce as it cooks.
Boiling water
Serves as the liquid base of the sauce, which the flour thickens.

The step that matters

Boil the sauce for 10 minutes. Flour starch thickens the sauce as it heats, but it needs sustained boiling to fully cook. Stirring while adding the hot water helps prevent lumps, and a full boil removes the raw floury taste.

Swap the parsnip

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

  1. Shallotfits better
  2. Chivefits about as well
  3. Capsicumfits about as well
  4. Parsnipthe original

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