Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Butter Bean Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Soak the butter beans overnight, then cook in 2 quarts of boiling water for 2 hours.
Strain the beans and layer them in a well-buttered pie dish with chopped parsley, butter, pepper, and salt.
Repeat the layers until the dish is nearly full, then add a little stock mixed with browning sauce.
Make the pastry and bake
For the pastry, rub the butter into the flour, then add baking powder and salt.
Add just enough cold water to form a dough that can be rolled out.
Cover with pastry and bake at 350°F (175°C) until golden brown.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter beans
- Form the bulk of the filling, giving it body and a creamy, starchy texture when cooked.
- Butter
- Adds richness and flavour to the filling and helps make the pastry tender and flaky.
- Flour
- Provides the structure of the pastry dough once mixed with water.
- Baking powder
- Releases gas during baking so the pastry rises and becomes lighter.
- Cold water
- Binds the flour and butter into a dough without developing excess gluten.
The step that matters
Add just enough cold water to form a dough. Too much water develops gluten and makes the pastry tough, while cold water keeps the butter solid so the pastry stays flaky.
Swap the beans
How well each one fits the dish's main ingredients (butter, parsley, pepper, sauce, flour):

- Beansthe original
Fit is the average pairing score against butter, parsley, pepper, sauce, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
