Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Provides the meaty body of the sauce and savory browned flavor when seared.
- Dried mushrooms
- Adds deep savory, umami flavor to the sauce, especially from their soaking liquid.
- Onions
- Soften and sweeten as they cook, forming the flavor base of the sauce.
- Tomatoes
- Supply acidity, moisture and body that make up the bulk of the sauce.
- Olive oil
- Carries fat-soluble flavors and helps onions and beef brown in the pot.
The step that matters
Browning the beef. Searing beef over medium heat until browned triggers the Maillard reaction, building deep savory flavor. Crowding the pan or stopping early leaves the meat grey and the sauce flat.
