Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the mixture into a creamy, spoonable body.
- Onion
- Adds sweetness and savory depth as it browns in the butter.
- Strained tomato
- Provides the liquid base and gentle acidity for the dish.
- Diced meat
- Adds savory, meaty flavor and some chew to each bite.
- Mushrooms
- Contribute earthy flavor and moisture.
The step that matters
Stirring in the eggs. Eggs thicken when heated gently, and when they get too hot or boil, they can curdle and turn grainy. Adding them gradually and keeping the heat low lets the proteins set smoothly into a creamy texture.
