Why it works: Biscuit and flour match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 889 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Peach Pie
Ingredients
Directions
Prepare
Line a deep dish with soda-biscuit dough or pie crust rolled to ¼ inch thick.
Peel and slice the peaches, then sprinkle them with sugar and a little flour.
If the peaches are not too juicy, add about 2 tablespoons of water.
Assemble and bake
Cover with the upper crust and secure the edges.
Bake until golden brown.
Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peaches
- Provide the main fruit filling, supplying bulk, juice and flavor.
- Sugar
- Adds sweetness and helps draw out juice that forms the filling's syrup.
- Flour
- Thickens the peach juices so the filling holds together when baked.
- Soda-biscuit dough or pie crust
- Forms the structure that holds the filling, browning to a golden crust.
The step that matters
Adding water only when the peaches are not too juicy. Peaches release liquid as they sit with sugar. Extra water on already juicy fruit thins the filling and can leave the bottom crust soggy, so check the juice before adding any.
Swap the peach
How well each one fits the dish's main ingredients (biscuit, sugar, flour, cream):
- Raisinfits better
- Vanillafits better
- Blueberryfits better
- Peachthe original
Fit is the average pairing score against biscuit, sugar, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
