Scotch Haggis

Ingredients

Directions

Prepare the stomach and pluck

  1. Wash the sheep's stomach well and soak it in cold salt water for several hours.

  2. Turn the stomach inside out, scald it in boiling water, scrape it quickly, and let it remain in water until needed.

  3. Clean the sheep's pluck thoroughly and pierce the heart and liver to let the blood run out.

  4. Boil the liver and lights for 1½ hours, then put them into fresh water.

  5. During the last ½ hour, boil the rest of the pluck with them.

  6. Trim away skins and discolored parts, grate the liver, and mince the rest finely.

Make the filling

  1. Add the suet, onions, oatmeal (or crumbled oat‑cakes), salt, pepper, nutmeg, and cayenne.

  2. Moisten the mixture with gravy and lemon juice, then fill the prepared stomach, leaving room for swelling.

Cook and serve

  1. Sew it securely and plunge it into boiling water, boiling gently for 3 hours.

  2. Prick the haggis with a needle occasionally, especially in the first half hour, to let air out.

  3. Serve hot without sauce or gravy.

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

What each ingredient does

Oatmeal
Absorbs liquid and gives the haggis its crumbly, bound texture.
Suet
Adds fat that keeps the filling moist and rich as it cooks.
Onions
Add savoury sweetness and aroma to the filling.
Sheep's pluck
Forms the meaty base that gives the haggis its main flavour and body.
Gravy
Moistens the filling so it stays tender and binds the mixture.

The step that matters

Pricking the haggis. Air and steam expand inside the stomach as it cooks; pricking early lets them escape so the casing does not burst.

Swap the onion

How well each one fits the dish's main ingredients (liver, pepper, nutmeg, lemon):

  1. Spinachfits better
  2. Carrotfits better
  3. Capsicumfits better
  4. Onionthe original

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