Why it works: Thyme and parsley 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 ↓
Fricassee of Mushrooms
Ingredients
Directions
Prepare the mushrooms
Put firm peeled mushrooms into boiling water for a moment.
Transfer the mushrooms to ice water.
Drain and wipe the mushrooms dry.
Make the gravy
In a saucepan, melt butter over medium heat and add the mushrooms.
Sprinkle in flour, white pepper, salt, thyme, and parsley; stir to combine.
Pour in stock and let simmer for 20 minutes.
Strain the gravy, then mix in the beaten egg yolks and lemon juice.
Serve
Break hot biscuits in half and place on a heated dish.
Carefully lay the mushrooms on the biscuits.
Pour the gravy over the mushrooms and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Firm mushrooms
- Provide the main body and bite of the dish.
- Butter
- Adds richness and carries flavor when melted with the mushrooms.
- Flour
- Thickens the stock into a smooth gravy as it simmers.
- Stock
- Forms the liquid base of the gravy, building savory flavor.
- Egg yolks
- Enrich and thicken the gravy when stirred in at the end.
- Lemon juice
- Adds acidity that brightens the rich gravy.
The step that matters
Mixing in the egg yolks. Egg yolks thicken when heated, so adding them to a very hot gravy can scramble them. Stirring them in off the heat, after straining, helps keep the gravy smooth.
Swap the white pepper
How well each one fits the dish's main ingredients (mushroom, butter, flour, thyme, parsley, biscuit, egg):
- Capersfits better
- Marjoramfits better
- Nutmegfits better
- White pepperthe original
Fit is the average pairing score against mushroom, butter, flour, thyme, parsley, biscuit, egg. Candidates are from the same food group and used in at least 100 recipes.
