Why it works: Parsley and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Sheep’s Brains with Parsley Sauce
Ingredients
Directions
Prepare the brains
Soak the brains in salt water for about 2 hours.
Remove the skin and fibers from the brains.
Cover the brains with boiling water and boil for a few minutes.
Replace the brains in fresh cold water until cold.
Poach the brains
Put the brains into boiling stock, add sliced onion and carrot, bay leaf, salt, and pepper.
Simmer gently for about 20 minutes.
Make the parsley sauce
Melt the butter in a stewpan, add the flour, and cook for a few minutes without browning.
Drain the brains and strain the stock into the flour and butter, stirring until boiling.
Simmer for about 10 minutes, then add seasoning.
Reheat the brains in the sauce, and just before serving, add 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 tender, delicate main protein that is poached and served in the sauce.
- Butter
- Enriches the sauce with fat and flavor, and forms the base of the roux.
- Flour
- Thickens the stock into a smooth sauce when cooked with the butter.
- White stock
- Poaches the brains and forms the liquid base of the sauce, adding savory flavor.
- Lemon juice
- Adds acidity that brightens the rich sauce and balances its fattiness.
- Parsley
- Adds fresh, herbal aroma and color to the finished sauce.
The step that matters
Cook the flour and butter without browning. Cooking the roux gently for a few minutes removes raw flour taste and gives full thickening power; browning would change the sauce's color and flavor.
