Roasted 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. Clean the potatoes thoroughly.

  2. Nick a small piece out of the skin.

Roast

  1. Roast in a 400°F (200°C) oven.

  2. Rub a little butter over the skin to make them crisp.

What each ingredient does

Potatoes
Provide the starchy flesh that becomes fluffy inside while the skin roasts.
Butter
Adds fat to the skin, helping it brown and crisp in the oven.

The step that matters

Nick a small piece out of the skin. The nick lets steam escape while the potato roasts, so it does not build pressure and split the skin unevenly. Keeping the skin intact until it is crisp gives a better texture.
