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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Line a deep dish with soda-biscuit dough or pie crust.
Fill and assemble
Fill with pared peaches, sprinkled with sugar and a little flour.
If the peaches are not too juicy, add about 2 tablespoons of water.
Place the upper crust on top and secure the edges.
Bake and serve
Bake at 400°F (200°C) until golden.
Serve with cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peaches
- Provide the fruit filling and its juice, which softens as the pie bakes.
- Sugar
- Adds sweetness and helps draw out juice from the peaches as they cook.
- Flour
- Thickens the peach juices so the filling sets rather than running out.
- Soda-biscuit dough or pie crust
- Forms the structure that holds the filling and browns to a golden finish.
The step that matters
Add water only if the peaches are not too juicy. Peaches release liquid as they bake, and flour can only thicken so much. Adding water to already juicy fruit can make the filling thin and soggy, so judge the juiciness first.
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.
