Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Herring Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Scale, gut, and clean the herring, then remove heads, fins, and tails.
Make a pie crust and cover your dish with it.
Assemble
Season the herring with mace, pepper, and salt.
Place butter at the bottom of the dish, then add a row of herring.
Dice the apple and onion, and layer them over the herring.
Bake
Add a little butter on top, pour in some water, cover with the lid, and bake well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herring
- Forms the main filling, with rich flesh that becomes tender as it bakes.
- Butter
- Adds richness and helps keep the fish moist in the covered dish.
- Apple
- Adds mild sweetness and moisture that softens as the pie bakes.
- Onion
- Adds savory depth and aroma as it cooks with the fish.
- Mace
- Adds a warm, aromatic spice flavor that complements the fish.
The step that matters
Covering and baking the dish. Covering traps steam so the fish cooks gently in its own juices and the water. Baking long enough ensures the fish is cooked through and the layers are tender.
Swap the mace
How well each one fits the dish's main ingredients (butter, apple, onion, pepper):
- Sagefits better
- Thymefits better
- Clovefits better
- Macethe original
Fit is the average pairing score against butter, apple, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
