Ingredients

Directions

Prepare

  1. Scrape and wash the parsnips.

  2. Boil the parsnips in salted water with a little vinegar until tender.

  3. Strain off the water and let the parsnips sit in a saucepan to evaporate excess moisture.

Mash and serve

  1. Add a lump of butter, season with coarse sea salt and white pepper, and mash until smooth.

  2. Serve as a vegetable or garnish for boiled meats.

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

What each ingredient does

Parsnips
Form the main body of the dish, becoming soft and mashable once boiled.
Butter
Adds richness and a smoother, silkier texture to the mash.

The step that matters

Letting the parsnips sit after straining. Excess water left in the parsnips makes the mash loose and watery. Letting them sit in the warm saucepan allows surface moisture to evaporate, so the mash holds its shape and tastes concentrated.

Swap the parsnip

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

  1. Mustardfits better
  2. Capsicumfits better
  3. Shallotfits better
  4. Parsnipthe original

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