Why it works: Beef and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Ragout of Beef a LA Mode
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the sauce
In a pot, melt the butter over medium heat.
Add the flour and stir to form a roux.
Gradually add the stock or gravy, stirring constantly until smooth.
Finish and simmer
Add the beef pieces, Worcestershire sauce, mushroom catsup, salt, and pepper.
Simmer until heated through and flavors meld, about 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main body and meaty flavor of the ragout.
- Butter
- Adds fat and richness and starts the roux.
- Flour
- Thickens the liquid into a smooth sauce when cooked with butter.
- Stock or gravy
- Forms the liquid base that becomes the sauce.
The step that matters
Adding the stock or gravy to the roux. Adding liquid gradually while stirring constantly keeps the starch dispersed, so the sauce becomes smooth instead of lumpy.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
