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, or Pie-plant 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Chop the rhubarb finely and place it in a pudding dish.
Sprinkle sugar over the rhubarb.
Make the batter
In a bowl, mix sour milk, eggs, butter, and baking soda.
Gradually add flour until the batter is thick like cake batter.
Bake and serve
Spread the batter over the rhubarb.
Bake until done, about 30-40 minutes.
Invert onto a platter so the rhubarb is on top.
Serve with additional sugar and cream.

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 layer that sits on top after inverting the pudding.
- Sugar
- Sweetens the rhubarb and balances its tartness.
- Sour milk
- Adds acidity that reacts with baking soda to help the batter rise.
- Eggs
- Bind the batter and add structure as it sets in the oven.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lifts the batter.
- All-purpose flour
- Builds the batter's structure so it sets into a cake-like pudding.
The step that matters
Gradually add flour until the batter is thick like cake batter. Adding flour gradually lets you judge the batter's thickness. Too much flour makes the pudding dense, while too little leaves it thin and soggy, so the batter needs to set into a cake-like texture.
Swap the rhubarb
How well each one fits the dish's main ingredients (sugar, milk, egg, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Rhubarbthe original
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.
