Roast Beef and 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. Preheat the oven to 400°F (200°C).

Roast

  1. Place the sirloin in the oven, timing it according to its size.

  2. One and a half hours before serving, peel the potatoes and place them around the beef in the pan.

  3. If the potatoes are large, cut them in half lengthwise.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

What each ingredient does

Sirloin beef roast
Forms the main protein; slow oven heat cooks it through while surface browns.
Potatoes
Absorb drippings from the beef, becoming tender and browned as they roast beside it.

The step that matters

Timing the beef and potatoes. Roast size determines cooking time, and potatoes added too early overcook while too late they stay firm. Timing both to finish together keeps the meat and potatoes ready at the same moment.
