Why it works: Leek and cauliflower share more aroma than cooks usually use. They rank in the top 3% of all ingredient pairs, and cooks put them together in 28 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard, giving the quiche its firm structure as they cook.
- Cheese
- Adds richness and fat, and melts into the custard for a creamy texture.
- Low-fat milk
- Provides liquid that combines with the eggs to form a tender custard.
- Leek
- Adds mild onion-like sweetness and aroma to the filling.
- Cauliflower
- Adds bulk and a mild, tender vegetable texture to the filling.
The step that matters
Baking until the knife comes out clean. Eggs set as their proteins coagulate with heat. Pulling the quiche too early leaves a runny custard, while overbaking makes it dry and rubbery.
