Why it works: Thyme and basil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,768 recipes. Both carry terpineol, which smells pine, woody. The science ↓

Ingredients
Directions
Prepare
Preheat oven to 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard and give the quiche its structure as they cook.
- Olive oil
- Carries the onion's flavour and keeps the onion from sticking while it softens.
- Spinach
- Adds the main vegetable body and moisture to the filling.
- Mozzarella cheese
- Melts into the custard, adding richness and a stretchy, creamy texture.
- Pecorino romano cheese
- Adds salty, sharp flavour and helps the filling brown lightly on top.
- Onion
- Sweetens as it cooks and adds savoury depth to the filling.
The step that matters
Bake until the centre is set. Eggs set as their proteins coagulate with heat. Pulling the quiche too early leaves a loose, wet centre, while overbaking makes the custard rubbery and dry.
Swap the clove
How well each one fits the dish's main ingredients (olive, onion, spinach, egg, garlic, thyme, basil):
- Oreganofits better
- Parsleyfits better
- Marjoramfits better
