Why it works: Rhubarb and flour match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 670 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Strawberry 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
Preheat the oven to 400°F (200°C).
Mix the sugar and flour in a bowl.
Assemble and bake
Fill the pie crust with the strawberries and rhubarb.
Dot the top with bits of butter.
Cover the pie and bake until bubbly.

Flour and butter 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
- Strawberries
- Provide the main fruit flavor and bulk of the filling.
- Rhubarb
- Adds tartness that balances the sweetness of the sugar.
- Sugar
- Sweetens the filling and helps draw out juices as it cooks.
- Flour
- Thickens the juices so the filling sets rather than running.
- Butter
- Adds richness and fat to the top of the pie.
The step that matters
Mix the sugar and flour before filling. Flour needs to be evenly distributed among the fruit so it can thicken the released juices. Clumps can leave pockets of raw starch, and an uneven mix can leave the filling runny in some spots and stiff in others.
Swap the rhubarb
How well each one fits the dish's main ingredients (sugar, flour, butter):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits better
- Rhubarbthe original
Fit is the average pairing score against sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
