Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Chaudfroid Sauce
Ingredients
Directions
Make the sauce
Put two tablespoonfuls of butter into a saucepan.
When it bubbles add two tablespoonfuls of flour.
Let it cook well, but not brown; stir all the time.
Add two cupfuls of chicken or veal stock, and stir until well thickened.
Season with salt and pepper.
Add a half box or one ounce of gelatin that has soaked an hour in a half cupful of cold water. Stir until the gelatin has dissolved.
Strain the sauce.
Add yolks of three eggs just before removing from the fire to give yellow color.
Test and adjust
Let it just begin to stiffen before using it.
Put a little on ice to test firmness.
If it is too stiff add a little more stock; if not hard enough add a little more gelatin.
Ensure the sauce is firm enough to hold its place without running.
Vary and apply
For brown chaudfroid, brown the roux and dilute with beef stock.
Add a few drops of kitchen bouquet for deeper color.
Pour sauce over boned chicken or other meats to give a smooth surface.
Decorate with truffles for ornamental cold dishes.
Before covering a galantine with chaudfroid, fill irregularities with sauce set on ice.
Ensure the surface is even before turning over the galantine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the roux with fat and flavor, giving the sauce a smooth, rich body.
- Flour
- Thickens the sauce as its starch gelatinises in the butter and stock.
- Chicken or veal stock
- Forms the liquid base of the sauce and adds savory flavor.
- Gelatin (in the method)
- Sets the cooled sauce so it clings to meat and holds its shape.
- Eggs
- Yolks add richness and a yellow color to the sauce.
The step that matters
Let it just begin to stiffen before using it. Gelatin sets as the sauce cools, so if it is too cold or too stiff it becomes lumpy and will not coat smoothly, while if it is too warm it runs off the meat. Testing a little on ice shows when it is ready.
