Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set with gentle heat to form the main structure and body of the dish.
- Onions
- Browning adds savory sweetness and aroma to the dish.
- Sweet cream
- Adds moisture and richness, keeping the eggs tender as they cook.
The step that matters
Cover and cook for 3 minutes. Egg proteins set as they heat, so the time decides whether the eggs turn out tender or overcooked. Covering traps steam, helping the tops set evenly.
