Why it works: Onion and potato 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 ↓
Clam 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.
Make the filling
Fry diced salt pork in a skillet until the fat is rendered and just before it colors.
Add the chopped onion to the skillet.
Add diced potatoes, boiling water, and black pepper to the skillet.
Cover and cook until the potatoes are almost tender.
Remove the skillet from heat.
Stir in the clams and their strained juice.
Pour the mixture into a well-greased deep dish.
Make the crust
In a bowl, mix and sift the flour, salt, and baking powder.
Rub in the lard until crumbly.
Add milk to form a soft dough.
Roll the dough out to ½ inch thick.
Bake the pie
Cover the pie with the dough.
Brush the dough with milk.
Bake at 400°F (200°C) for 35 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat that flavors the filling and helps cook the onion and potatoes.
- Raw potatoes
- Add starch and bulk, becoming tender and thickening the filling as they cook.
- Raw clams
- Provide the main seafood flavor and tender chewy texture in the filling.
- All-purpose flour
- Forms the structure of the dough, setting firm as it bakes.
- Baking powder
- Releases gas during baking so the crust rises and becomes light.
- Lard
- Rubbed into flour to tenderize the crust and keep it flaky.
The step that matters
Rub in the lard until crumbly. Lard coats flour particles and limits gluten formation, so the crust stays tender and flaky rather than tough. Stopping when the mixture is crumbly keeps the fat in distinct pieces.

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