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

  1. In a pot, melt the butter over medium heat.

  2. Add the flour and stir to form a roux.

  3. Gradually add the stock or gravy, stirring constantly until smooth.

Finish and simmer

  1. Add the beef pieces, Worcestershire sauce, mushroom catsup, salt, and pepper.

  2. 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.
