Why it works: Rhubarb and almond match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 117 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Strawberry Rhubarb Crumble
six 1 ¼‑cup custard cupsIngredients
Directions
Prepare the filling
Preheat oven to 400 °F.
Mix rhubarb, strawberries, 1/2 cup sugar, cornstarch, and lemon juice in a large bowl. Toss well to coat.
Divide mixture equally among six 1 ¼‑cup custard cups.
Make the topping
Mix butter, almond paste, and remaining 1/3 cup sugar in a processor until well blended. Transfer butter mixture to a medium bowl.
Add flour. Using fingertips, work flour into butter mixture until moist clumps form.
Bake and serve
Sprinkle topping over rhubarb and strawberries, dividing equally.
Place custard cups on a baking sheet.
Bake until filling bubbles and topping is golden, about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides tartness and bulk, softening into the filling as it bakes.
- Strawberries
- Add sweetness, aroma and juice that forms the bubbling filling.
- Cornstarch
- Thickens the juices released by the fruit so the filling sets rather than runs.
- Butter
- Adds fat and richness, and helps the topping brown and turn crisp.
- Almond paste
- Adds moisture, sweetness and nutty flavour to the topping.
- All-purpose flour
- Gives the topping structure so it forms clumps that bake into a crumbly texture.
The step that matters
Work the flour into the butter mixture until moist clumps form. Overworking warms the butter and develops gluten, making the topping dense and tough instead of crumbly. Stop once clumps form so the butter stays cold enough to crisp as it bakes.
