Mutton Sheep’s Brains with Parsley Sauce

Ingredients

Directions

Prepare the brains

  1. Soak the brains in salt water for about 2 hours, then remove the skin and fibers.

  2. Cover the brains with boiling water and boil for a few minutes.

  3. Replace the brains in fresh cold water until cold, then put them into boiling stock.

Make the sauce

  1. Add sliced onion, carrot, bay leaf, salt, and pepper to taste, and simmer gently for about 20 minutes.

  2. Melt the butter in a saucepan, add the flour, and cook for a few minutes without browning.

  3. Strain the stock into the flour and butter mixture, stir until boiling, and simmer for about 10 minutes.

  4. Reheat the brains in the sauce, and just before serving, add the lemon juice.

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

What each ingredient does

Sheep's brains
Provide the main protein, which turns tender and delicate after gentle simmering.
Butter
Enriches the sauce and carries flavour, giving it a smooth, rich mouthfeel.
Flour
Thickens the stock into a smooth sauce when cooked briefly with butter.
White stock
Forms the liquid base of the sauce and cooks the brains gently.
Lemon juice
Adds acidity that brightens the rich sauce and balances its flavour.

The step that matters

Cook the flour and butter without browning. Cooking the roux only a few minutes lets the starch swell and thicken the stock smoothly. Browning would change the colour and flavour and weaken the sauce's thickening power.

Swap the onion
