Koasting Meat

Ingredients

Directions

Prepare

  1. Hang the mutton in a cool, dry place for 4 to 10 days depending on the weather.

  2. Prepare a brisk fire for roasting.

Roast

  1. Position the mutton 12 inches from the fire for the first 30 minutes.

  2. Move the mutton to 8 inches from the fire for the next hour.

  3. Place the mutton closer to the fire for the last 30 minutes.

  4. Dredge the mutton lightly with flour and salt halfway through cooking and again near the end.

Serve

  1. Make gravy using the same method as for sirloin of beef, using less water.

  2. Serve with vegetables and onion sauce if desired.

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

What each ingredient does

Mutton
Hanging ages the meat, and roasting it over a fire gives it a browned, savoury crust.
Flour
Dredging coats the outside, helping form a crisp, browned crust during roasting.

The step that matters

Dredge the mutton halfway through and again near the end. Flour applied during roasting forms a coating that browns and crisps on the surface; adding it only once would leave the later part of the roast less crusted.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (mutton, flour, sauce):

  1. Shallotfits better
  2. Turnipfits better
  3. Arrowrootfits better
  4. Onionthe original

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