Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fish Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the mixture
In a bowl, combine the chopped fish, mashed potatoes, and finely chopped suet.
Season the mixture with coarse sea salt and black pepper.
Add the eggs and enough milk to achieve a very thick batter consistency. Mix well until fully combined.
Bake and serve
Transfer the mixture to a greased pie dish.
Bake in the preheated oven for 1 to 1.5 hours.
Serve in the dish in which it was baked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and help it set as it bakes.
- Mashed potatoes
- Add body and softness, giving the filling a thick, spoonable texture.
- Suet
- Adds fat that keeps the filling moist and rich as it cooks.
- Milk
- Loosens the mixture to a thick batter consistency and adds moisture.
The step that matters
Add the milk gradually to a very thick batter. Too much liquid makes the filling loose and slow to set, while too little leaves it dry and crumbly. Adding milk a little at a time lets you reach a thick, spoonable consistency that holds together when baked.
Swap the potato
How well each one fits the dish's main ingredients (fish, egg, milk, pepper):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Tomatofits less well
Fit is the average pairing score against fish, egg, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
