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. Season the mashed potatoes with salt and pepper.

  2. Add the melted butter and half of the egg, then mix well.

  3. Form the mixture into an oval or round border shape.

Bake

  1. Brush the top with the remaining egg.

  2. Place on a greased baking sheet and bake at 400°F (200°C) until brown.

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

What each ingredient does

Mashed potatoes
Form the main body of the border, giving it bulk and a soft, fluffy texture.
Butter
Adds richness and moisture, helping the potatoes stay tender and carry flavour.
Egg
Binds the mixture so it holds its shape, and the beaten top layer helps it brown.

The step that matters

Brush the top with the remaining egg. Egg proteins set and brown in the oven, so an even coat gives a glossy, golden surface. Patchy coverage can leave pale spots.

Swap the potato

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

  1. Capsicumfits better
  2. Asparagusfits about as well
  3. Chivefits about as well
  4. Potatothe original

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