Why it works: Leek and potato work together. They rank in the top 6% of all ingredient pairs, and cooks put them together in 30 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Leek 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 the vegetables
Dice the potatoes and leeks.
Parboil them in 1 pint of water, adding the herbs, butter, and seasoning.
Assemble and bake
Place the vegetables in a pie dish.
Make a batter with the milk, eggs, and flour, then pour it over the vegetables.
Mix everything well and bake the pie for 1.5 to 2 hours at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leeks
- Provide the main savoury body and mild onion-like flavour of the pie.
- Potatoes
- Add starch and bulk, giving the filling a soft, substantial texture.
- Eggs
- Help the batter set during baking, binding it into a custard-like structure.
- Fine wheat flour
- Thickens the milk and egg batter so it holds together around the vegetables.
- Milk
- Forms the liquid base of the batter, adding moisture and richness.
- Butter
- Adds fat for richness and flavour in the parboiled vegetables.
The step that matters
Mix everything well before baking. The batter must be evenly distributed through the vegetables, because the eggs and flour set during baking and uneven mixing leaves pockets of loose batter or dry vegetables.
Swap the leek
How well each one fits the dish's main ingredients (potato, nutmeg, milk, pepper, wheat, flour, egg):

Fit is the average pairing score against potato, nutmeg, milk, pepper, wheat, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
