Roast Lamb with Caper Sauce

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Season the leg of lamb with salt and pepper.

  3. Rub the lamb with olive oil and place it in a roasting pan.

Roast and serve

  1. Roast the lamb for about 1.5 to 2 hours, or until it reaches your desired doneness.

  2. In a small saucepan, heat capers in a little olive oil for a few minutes.

  3. Serve the lamb with the caper sauce drizzled on top.

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.

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

What each ingredient does

Leg of lamb
Forms the main body of the dish and carries most of its flavor and texture.
Capers
Add a sharp, briny acidity that cuts through the richness of the lamb.
Olive oil
Carries heat and adds moisture and fat, helping the lamb brown and the capers soften.

The step that matters

Roasting to doneness. Lamb is best judged by internal temperature rather than time alone, since the cut's size and starting temperature change how long it takes. Overcooking dries the meat and makes it tough, so checking doneness near the end of the roast matters.

Swap the capers

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

  1. Rosemaryfits better
  2. Parsleyfits better
  3. Garlicfits better
  4. Capersthe original

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