Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Rhubarb 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
Preheat the oven to 350°F (175°C).
Chop enough rhubarb to nearly fill your baking dish and sprinkle sugar over it.
Make and bake
In another bowl, mix sour milk, eggs, butter, baking soda, and enough flour to make a cake batter.
Spread the batter over the rhubarb.
Bake until done.
Serve
Turn out onto a platter upside down and serve with cream and sugar.

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 contrasts with the sweet cake layer.
- Sugar
- Sweetens the rhubarb and helps draw out its juices as it bakes.
- Sour milk
- Its acidity reacts with baking soda so the batter rises and stays tender.
- Eggs
- Add structure to the batter and help it set as it bakes.
- Butter
- Adds fat for richness and a tender crumb in the batter.
- Baking soda
- Reacts with the acid in sour milk to produce gas that lifts the batter.
The step that matters
Spreading the batter over the rhubarb. Batter spread too thinly or unevenly can bake dry in spots, while the fruit may release juice that makes the bottom soggy if the batter is not evenly covering it.
Swap the rhubarb
How well each one fits the dish's main ingredients (sugar, milk, egg, butter, flour):

Fit is the average pairing score against sugar, milk, egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
