The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: 2-nonenal (fatty, green).
Egg and lemon barely smell alike, yet cooks put them together in 44,316 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten and set to bind the filling and give the tortilla its body.
- Lemon juice
- Adds a bright acidity that balances the rich eggs and spinach.
The step that matters
Let the tortilla set. Eggs firm up as their proteins coagulate with heat. If the tortilla is turned or moved before the surface has set, it will tear or slump, so wait until the top is no longer runny.
“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.
