Moulded Mashed 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 and mould

  1. Prepare mashed potatoes with milk, butter, and seasoning.

  2. Press the potatoes firmly into a fluted mold that has been wet with cold water.

Turn out and bake

  1. Turn out the molded potatoes onto a dish.

  2. If desired, brush the potatoes with beaten egg before placing them in the oven.

  3. Place the dish in a 400°F (200°C) oven for five minutes.

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

What each ingredient does

Mashed potatoes
Provide the starchy body that holds the mould's shape once packed and set.
Milk
Adds moisture and softness, keeping the potato mixture smooth and easy to press.
Butter
Adds fat for richness and a smoother, silkier texture.
Beaten egg
Brushed on optionally, it promotes golden browning and a glossy surface in the oven.

The step that matters

Press the potatoes firmly into the wet mold. Firm packing removes air pockets so the potatoes hold their shape when turned out. A thin film of cold water on the mold keeps the potatoes from sticking to the metal.

Swap the potato

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

  1. Potatothe original
  2. Asparagusfits about as well
  3. Chivefits less well
  4. Leekfits less well

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