On Baking Meat

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. Parboil and peel the potatoes.

  3. Shred the onion.

Bake

  1. Place the leg of mutton in a baking dish.

  2. Add the parboiled potatoes and shredded onion around the meat.

  3. Season with coarse sea salt and add butter on top.

  4. Cover the dish and bake for 1.5 to 2 hours, or until the meat is tender.

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

What each ingredient does

Leg of mutton
Provides the main meat, which becomes tender and juicy during slow covered baking.
Potatoes
Absorb meat juices and fats, becoming soft and flavorful as they bake.
Onion
Softens and sweetens as it bakes, adding aroma to the meat juices.
Butter
Adds fat that enriches the juices and promotes gentle browning on top.

The step that matters

Cover the dish and bake until the meat is tender. Covering traps steam so the tough connective tissue in the mutton breaks down slowly with moist heat. Checking for tenderness rather than relying only on the clock matters, because cuts vary in size and thickness.

Swap the onion

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

  1. Onionthe original
  2. Leekfits about as well
  3. Chivefits about as well
  4. Asparagusfits about as well

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