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).

  2. Place the rack of lamb in a pan with the potatoes.

  3. Season the lamb and potatoes with salt and pepper.

  4. Spread the butter over the lamb and potatoes.

Roast and serve

  1. Roast for about 40 minutes, turning and basting frequently.

  2. Arrange the potatoes around the lamb on a platter.

  3. Sprinkle with chopped parsley before serving.

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

What each ingredient does

Rack of lamb
Forms the main cut; its fat and meat cook and brown in the oven.
Potatoes
Absorb rendered lamb fat and juices, becoming tender and savory as they roast.
Butter
Adds fat that promotes browning and a rich flavor on the lamb and potatoes.

The step that matters

Turning and basting frequently. Turning and basting during roasting spreads fat and juices over the surface, promoting even browning and keeping the meat moist as it cooks.

Swap the potato

How well each one fits the dish's main ingredients (lamb, pepper, butter, parsley):

  1. Potatothe original
  2. Carrotfits about as well
  3. Okrafits less well
  4. Shallotfits less well

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