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 and bake the batter
In a bowl, mix sour milk, eggs, butter, and baking soda.
Add flour gradually until the batter is thick like cake batter.
Spread the batter over the rhubarb.
Bake until done, about 30-40 minutes.
Serve
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 tart flavor and moisture that cooks into the topping layer.
- Sour milk
- Its acidity reacts with baking soda to help the batter rise.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lightens the batter.
- Flour
- Gives the batter body and structure so it bakes like a cake.
- Butter
- Adds fat for tenderness and rich flavor in the batter.
The step that matters
Adding the flour gradually. The batter should be thick like cake batter. Too much flour makes it dense and tough, while too little leaves it runny and unable to hold its structure over the rhubarb.
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

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.
