Roast Lamb

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.

Prepare

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

  2. Place the lamb in a dripping pan and dash with boiling water.

Roast

  1. Cook for 15 minutes per pound, basting often.

  2. Ten minutes before removing, dredge the lamb with flour and baste with butter.

Make the gravy

  1. Pour off excess fat, then make gravy in the pan and mix in currant jelly.

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

What each ingredient does

Lamb
Forms the main body of the dish and supplies the meat and fat that drip into the pan.
Flour
Dredged over the surface to help form a browned crust and thicken the gravy.
Butter
Basting fat that adds moisture and richness and helps the surface brown.
Currant jelly
Adds sweetness and acidity to the gravy, balancing the richness of the lamb fat.

The step that matters

Pour off excess fat before making gravy. Lamb renders a lot of fat into the pan. Leaving too much in makes the gravy greasy and thin, while the flour and pan juices need a controlled amount of fat to thicken and carry flavour.

Swap the currant

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

  1. Raisinfits better
  2. Coconutfits better
  3. Avocadofits better
  4. Currantthe original

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