Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Steamed Pudding
Ingredients
Directions
Prepare
In a large bowl, combine the raisins, eggs, sugar, flour, sour cream, baking soda, and cream of tartar, and mix until well combined.
Pour the mixture into a greased pudding mold.
Steam
Bring water to a boil in a large pot.
Place the mold in the pot, cover, and steam for 2 hours without opening the lid.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as they set during steaming.
- Flour
- Provides the main structure of the pudding as it cooks.
- Baking soda
- Reacts with the acidic cream of tartar and sour cream to help the pudding rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda to produce lift.
- Sour cream
- Adds moisture and tang, and its acidity helps the leavening reaction.
- Sugar
- Sweetens the pudding and contributes to a moist, tender crumb.
The step that matters
Steam without opening the lid. Opening the pot lets steam escape and the temperature drop, which can stall the rise and leave the pudding dense or uneven. Keep the water at a steady simmer and keep the lid closed for the full two hours.
Swap the raisin
How well each one fits the dish's main ingredients (egg, sugar, flour, cream):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, sugar, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
