Parsnips and Potatoes

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Combine mashed potatoes and parsnips in a bowl.

  2. Add pepper, salt, and butter; mix well.

  3. Heat the mixture in a saucepan over low heat for 1 minute.

Bake and serve

  1. Press into a greased baking dish.

  2. Brown in the oven at 400°F (200°C).

  3. Cut into squares.

  4. Serve hot in a vegetable dish.

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

What each ingredient does

Parsnips
Add body and a subtly sweet, earthy flavour to the mash.
Potatoes
Provide the starchy base that holds the mash together and gives it a soft texture.
Butter or dripping
Adds fat for richness, smooth texture, and browning on the surface.

The step that matters

Brown in the oven at 400°F (200°C). Browning depends on surface dryness and heat. Too little heat leaves the mash pale and soft, while too long can dry it out. Watch the top closely for an even golden colour.

Swap the parsnip

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

  1. Capsicumfits better
  2. Chivefits better
  3. Onionfits better
  4. Parsnipthe original

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