Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Chicken Pie
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Cook the filling
Boil the chicken gently until it falls from the bones.
Cut the chicken into small pieces.
Cook the potatoes and onion in the chicken broth.
Make the pastry
Make a pastry with flour, lard, salt, and baking powder.
Add enough milk to form a soft dough.
Assemble and bake
Line a baking dish with the pastry.
Bake at 400°F (200°C).
Fill the dish with chicken, potatoes, and a small amount of broth.
Cover with pastry.
Brown in the oven at 400°F (200°C).
Finish and serve
Thicken the remaining broth.
Serve over the pie.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure of the pastry as its proteins and starches set when baked.
- Lard
- Coats flour particles to keep the crust tender and flaky rather than tough.
- Baking powder
- Releases gas during baking, helping the pastry rise and lighten.
- Milk
- Adds moisture so the flour hydrates into a soft, workable dough.
- Potatoes
- Add starch and body to the filling, making it hearty and substantial.
- Chicken
- Provides the main meat filling, contributing savoury flavour and bulk.
The step that matters
Adding the milk to the pastry. Stop mixing once the dough just holds together. Overworking flour develops gluten, which makes the crust tough rather than tender and flaky.
Swap the onion
How well each one fits the dish's main ingredients (flour, egg, milk, chicken, potato):
- Asparagusfits better
- Chivefits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against flour, egg, milk, chicken, potato. Candidates are from the same food group and used in at least 100 recipes.
