White Mushroom Soup
Ingredients
Directions
Make the veal stock
Gash the veal and break the bone in several places.
Combine the veal and water in a pot and bring to a slow boil, skimming carefully.
Add the vegetables and skim again when it boils.
Maintain a slow boil for 5 hours, then strain through muslin.
Make the soup
In a saucepan, melt the butter and flour together until bubbling, then cook for 1 minute while stirring.
Quickly pour in 2 quarts of hot veal stock while stirring, and boil for 1 minute until thick.
Stir in the boiled milk and cream without boiling.
The next day, heat the soup, skim it, and add the can of French mushrooms.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and stock into a smooth, velvety base for the soup.
- Butter
- Forms the roux with flour and adds richness and a rounded flavour.
- Cream
- Adds fat and a smooth, rich texture to the finished soup.
- Boiled new milk
- Adds body and mild sweetness, softening the savoury stock.
- Knuckle of veal
- Releases gelatin and flavour into the water during the long simmer, giving the stock body.
The step that matters
Stir in the milk and cream without boiling. Boiling dairy can make it curdle or separate and taste scorched, so the milk and cream should be stirred in off the boil and kept hot, not bubbling.
Swap the thyme
The recipe marks thyme as optional. How well each one fits the dish's main ingredients (veal, carrot, turnip, onion, clove, parsley, flour):
- Marjoramfits about as well
- Thymethe original
- Celeryfits about as well
- Capersfits about as well
Fit is the average pairing score against veal, carrot, turnip, onion, clove, parsley, flour. Candidates are from the same food group and used in at least 100 recipes.
