Why it works: Beans and potato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 655 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Potato Tartlets
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 shells
Line small tartlet molds with thin pie crust.
Fill the molds with dry beans and bake.
Remove the beans from the tartlets.
Fill and brown
Prepare the potatoes as for Regent.
Fill the tartlets with the prepared potatoes.
Sprinkle with bread crumbs and bits of butter.
Brown in a hot oven at 400°F (200°C).
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Thin pie crust
- Forms the tender pastry case that holds the filling.
- Dry beans
- Weigh down the crust so it stays flat instead of puffing while it bakes.
- Potatoes
- Form the soft, moist filling inside the tartlets.
- Bread crumbs
- Absorb surface moisture and help the top turn crisp and golden.
- Butter
- Adds richness and helps the topping brown.
The step that matters
Fill the molds with dry beans and bake. The beans weigh the pastry down so it sets flat in the mold. Without them, the crust can puff up and shrink away from the sides as it bakes.
Swap the beans

Fit is the average pairing score against potato, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
