Why it works: Carrot and parsley 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 ↓
Ragout of Sweetbreads
Ingredients
Directions
Prepare the sweetbreads
Soak the sweetbreads in fresh water to remove blood, then blanch them.
In a stew pan, combine carrots, onions, veal parings, parsley, and young onions.
Add the sweetbreads and cover with a slice of bacon.
Moisten with bouillon, ensuring they do not swim in liquid.
Cover with buttered paper and boil.
Place the pot under a furnace with heat above and below.
Monitor to prevent overcooking; remove when done.
Make the sauce
If no sauce remains, strain the cooking liquid.
For a blanc sauce, mix butter with flour and add mushrooms.
Cook the mixture, skim, and add artichoke bottoms.
Finish and serve
Slice the sweetbreads.
Add the sliced sweetbreads to the sauce without boiling.
Before serving, thicken the sauce with egg yolks, minced parsley, lemon or verjuice, and a little butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein; their tender, delicate texture is the centre of the dish.
- Egg yolks
- Thicken the sauce as they set gently with heat, giving it a smooth, rich body.
- Butter
- Enriches the sauce with fat, adding richness and a silky mouthfeel.
- Bouillon
- Moistens the sweetbreads during cooking, adding savory flavour to the liquid.
- Lemon or verjuice
- Adds acidity that brightens the rich sauce and balances its fattiness.
The step that matters
Add the sweetbreads to the sauce without boiling. Egg yolks used to thicken a sauce will curdle and turn grainy if the sauce boils, so heat must stay gentle once the yolks are in.
Swap the onion
How well each one fits the dish's main ingredients (carrot, veal, parsley, butter, egg, lemon):
