Why it works: Rhubarb and raisin work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 47 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rhubarb 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).
Line a pie dish with the pastry.
Brush the pastry with egg white.
Fill and bake
Fill the dish with the rhubarb and scatter the sultana raisins among the fruit.
Sweeten generously with sugar.
Cover with a top crust and bake until golden.
Brush the top with egg white while hot to glaze the crust.
Serve
Let it cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the tart fruit base that gives the pie its main flavour and filling bulk.
- Sugar
- Sweetens the tart rhubarb and helps balance its acidity.
- Egg white
- Brushed on the crust to add a glossy, golden browned finish.
- Sultana raisins
- Add pockets of concentrated sweetness and chewy texture among the fruit.
The step that matters
Let it cool before serving.. Rhubarb releases a lot of juice as it cooks, and the filling thickens only as it cools. Cutting too early lets the juices run out and leaves the filling runny.
Swap the rhubarb
How well each one fits the dish's main ingredients (egg, raisin, sugar):
- Cinnamonfits better
- Nutmegfits better
- Rhubarbthe original
- Gingerfits about as well
Fit is the average pairing score against egg, raisin, sugar. Candidates are from the same food group and used in at least 100 recipes.
