Why it works: Olive and chard match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 320 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Apple-Chard Quiche
Ingredients
Directions
Cook the vegetables
Preheat oven to 375°F.
Heat oil and butter in large skillet over medium heat.
Reduce heat to medium-low, and sauté onions until caramelized, about 15 minutes.
Add Swiss chard, mushrooms, salt and pepper.
Increase heat to medium, and cook, stirring often, until mushrooms and chard are soft, about 7 minutes.
Make the filling
Combine apples, flour and nutmeg in mixing bowl, and toss to coat apples.
Combine eggs, cheese and milk in separate bowl, and beat until ingredients are well blended.
Fold in apple mixture.
Spoon chard mixture into pie crust.
Pour egg-cheese-apple mixture over top.
Bake and serve
Bake 35 to 45 minutes, or until cheese mixture is set and top is browned.
Cool slightly before slicing, and serve.

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 bind the filling so the quiche holds its slices.
- Jarlsberg cheese
- Melts into the custard, adding richness and savory flavor while helping it set.
- All-purpose flour
- Coats the apples and thickens the egg mixture slightly, helping it hold together.
- Skim milk
- Provides the liquid that the eggs set in, keeping the custard moist and tender.
- Ruby swiss chard
- Adds leafy bulk and earthy flavor that softens as it cooks down.
- Onion
- Caramelizes slowly, adding sweetness and depth to the filling.
The step that matters
Cook the onions slowly until caramelized. Low, steady heat lets the onion sugars brown gradually. Rushing with high heat scorches the onions before they turn sweet and deeply flavored, and extra moisture left in the vegetables can make the custard watery.
Swap the apple
How well each one fits the dish's main ingredients (olive, butter, onion, chard, mushroom, pepper, flour):
