Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fiddle Head Pie
Ingredients
Directions
Prepare
Pre‑cook pie crust for about 20 minutes.
Saute fiddle heads in olive oil until tender.
Assemble and bake
Place fiddle heads in pie crust, then top with cheese.
Blend eggs, mustard, half and half, and flour.
Pour the mixture over the fiddle heads and cheese.
Bake at 350 °F for 50 minutes.
Check doneness by inserting a knife; it should come out clean.
Let set for about 5 minutes before cutting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard so the filling firms up as it bakes.
- Half and half
- Adds moisture and richness to the custard, keeping the filling creamy.
- Cheddar cheese
- Melts through the filling and adds fat and savory flavor.
- Flour
- Thickens the egg mixture so it holds together when sliced.
- Fiddle heads
- Provide the main vegetable bulk and earthy flavor of the filling.
The step that matters
Check doneness with a knife. Eggs keep setting as the pie cools, so pulling it too early leaves a runny custard. A knife inserted near the center should come out clean before you remove it from the oven.
