Potatoes and Carrots

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Mash the boiled potatoes and carrots together.

  2. Beat the eggs well and mix them with the mashed vegetables.

  3. Add pepper and salt to taste.

Bake and serve

  1. Butter a mold and fill it with the mixture.

  2. Spread butter on top and bake for 30 minutes at 350°F (175°C).

  3. Turn out the dish and garnish with parsley.

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

What each ingredient does

Potatoes
Provide the starchy bulk that gives the bake its soft, mashed body.
Carrots
Add sweetness, colour and moisture to the mashed base.
Eggs
Bind the mashed vegetables so the bake holds its shape when turned out.
Butter
Adds richness and helps the top brown during baking.

The step that matters

Beat the eggs well before mixing. Well-beaten eggs blend evenly through the mash, so the binding sets uniformly and the bake does not split into wet and dry layers.

Swap the potato

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

  1. Parsnipfits about as well
  2. Capsicumfits about as well
  3. Leekfits about as well
  4. Potatothe original

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