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 and Tapioca Pudding
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the tapioca
Wash the tapioca and soak it in lukewarm water for 4 hours until it absorbs all the water.
Layer the pudding
Butter a pudding dish and cover the bottom with sliced rhubarb.
Sprinkle a heaping tablespoon of sugar over the rhubarb.
Scatter a teaspoon of chopped raisins on top of the rhubarb.
Add half of the soaked tapioca on top of the raisins.
Dot with butter and sprinkle with 2 tablespoons of sugar.
Layer more rhubarb, raisins and sugar, then add the remaining tapioca.
Dot with butter and sprinkle with sugar again.
Bake and serve
Bake covered at 350°F (175°C) for 1 hour until browned.
Serve hot with hard or liquid sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pearl tapioca
- Swells as it soaks and sets into a soft, thick body in the pudding.
- Rhubarb
- Provides tart acidity that balances the sugar and fruit flavour.
- Sugar
- Sweetens the pudding and helps the rhubarb caramelise and brown on top.
- Butter
- Adds richness and helps the top brown as it bakes.
The step that matters
Soak the tapioca fully. Pearl tapioca must absorb its water before baking; if it is under-soaked, the grains stay firm and the pudding will not set evenly.
Swap the rhubarb
How well each one fits the dish's main ingredients (sugar, raisin, butter):
- Cinnamonfits better
- Nutmegfits better
- Rhubarbthe original
- Gingerfits about as well
Fit is the average pairing score against sugar, raisin, butter. Candidates are from the same food group and used in at least 100 recipes.
