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 the potatoes

  1. Peel the potatoes, removing any spots, and place them in cold salted water as you peel.

  2. Once all potatoes are peeled, transfer them to clean cold water and boil until soft, skimming the pot as needed.

  3. Drain the potatoes and mash them finely.

Mash and brown

  1. Add 1 cup of milk or thin cream and a little more salt, or a bit of butter if desired.

  2. Smooth the mashed potatoes in a dish.

  3. Place the dish in a 400°F (200°C) oven or near the fire to brown.

  4. Slice the cold mashed potatoes an inch thick.

  5. Brown the slices in the oven like toast.

  6. Serve with butter.

What each ingredient does

Potatoes
Form the main body of the dish, mashing into a soft, starchy base.
Milk or thin cream
Adds moisture and richness, making the mash smooth and creamy.
Butter
Adds fat and flavour, giving the mash richness and a smooth mouthfeel.

The step that matters

Mashing the potatoes finely. Potatoes must be boiled until fully soft and drained well, since excess water or lumps make the mash watery or stiff. Mashing while still hot helps the starch stay smooth when milk is added.
