Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Blanquette of Lamb
Ingredients
Directions
Cook the lamb
Cut the lamb into pieces about 2 inches square.
In a stewpan, combine the lamb, onion, herbs, peppercorns, and a little salt.
Cover with cold water and cook gently for about 2 hours.
Make the sauce
Melt the butter in a separate pan, add the flour, and stir for a few minutes without browning.
Strain ½ pint of the cooking liquid from the meat and add it to the butter and flour mixture.
Stir until boiling, then simmer for a few minutes.
Beat together the egg yolk and cream or milk, then add to the sauce, stirring gently.
Cook for a few minutes without boiling to prevent curdling.
Serve
Arrange the meat on a hot dish, strain the sauce over it, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb
- Provides the meat that becomes tender during long, gentle cooking in liquid.
- Butter
- Enriches the sauce with fat and a smooth, rich mouthfeel.
- Flour
- Thickens the cooking liquid into a smooth sauce when cooked with butter.
- Egg yolk
- Enriches and thickens the sauce, giving it a silky texture.
- Cream or milk
- Adds richness and moisture, mellowing the sauce when combined with the yolk.
The step that matters
Adding the egg yolk and cream without boiling. Egg proteins set when heated, so if the sauce boils after the yolk goes in, it can curdle and turn grainy. Stirring gently and keeping it just below a boil keeps the sauce smooth.
Swap the onion
How well each one fits the dish's main ingredients (lamb, parsley, thyme, butter, flour, egg, cream):
