Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

Wash and peel the potatoes, cut a deep slice off one end of each, and scoop out some flesh.
Place a piece of butter in each potato hollow, then season with salt and pepper.
Replace the cut-off pieces as covers and trim the other end for stability.

Roast and serve

Set the potatoes upright in a baking pan with a little water to prevent burning.
Roast in a 300°F (150°C) oven, basting frequently, until cooked through.
Serve in the baking dish.

What each ingredient does

Potatoes: Form the edible body that softens into a tender, fluffy interior as it roasts.
Butter: Adds richness and moisture, melting into the potato hollow as it bakes.

The step that matters

Roast in a 300°F (150°C) oven, basting frequently, until cooked through. Low, slow heat cooks the potato interior evenly without scorching. Basting keeps the melted butter spreading over the flesh, preventing the surface from drying out before the center is tender.
