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 ↓
Cream of Mushrooms, Supreme
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the mushrooms
Clean and cut mushrooms into ½-inch pieces.
Place mushrooms in a stone jar and cover with cold water.
Cook in a 300°F (150°C) oven until tender.
Rub the cooked mushrooms through a fine sieve.
Make the soup
In a pan, braise shallots, carrot, and celery in butter for 15 minutes.
Add parsley, mace, and flour to thicken the soup.
Blend to a smooth paste.
Slowly incorporate veal broth.
Bring to a boil.
Reduce to a simmer and cook for 2 hours.
Skim off fat.
Strain.
Add mushroom pulp.
Season and finish
Season with salt, white pepper, and nutmeg.
Stir in cream before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main body, earthy flavour and pulp that thickens the soup.
- Butter
- Carries the flavour of the braised vegetables and adds richness.
- Flour
- Thickens the soup by binding with the liquid as it cooks.
- Veal broth
- Forms the liquid base and supplies savoury depth.
- Sweet cream
- Adds richness and a smooth, silky texture at the end.
The step that matters
Slowly incorporate veal broth. Adding broth gradually to the flour-and-butter paste lets it blend smoothly. Pouring it in all at once can leave lumps that are hard to remove.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, butter, shallot, carrot, celery, parsley, flour):
- Thymefits better
- Capersfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against mushroom, butter, shallot, carrot, celery, parsley, flour. Candidates are from the same food group and used in at least 100 recipes.
