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
Make the batter
In a large bowl, combine the raisins, eggs, sugar, flour, sour cream, baking soda, and cream of tartar, then 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
- Raisins
- Provide the bulk of the pudding and concentrated sweetness and chewy texture.
- Eggs
- Bind the batter and add structure as the pudding sets.
- Flour
- Forms the main structure of the pudding.
- Sour cream
- Adds moisture and a slight tang that keeps the crumb tender.
- Baking soda
- Reacts with the cream of tartar and acidic sour cream to produce gas that lifts the pudding.
- Cream of tartar
- Acid that activates the baking soda, helping the pudding rise.
The step that matters
Steam without opening the lid. Lifting the lid lets steam escape and the pot temperature drop, which interrupts even cooking and can cause the pudding to sink or turn dense. Keeping the lid on holds steady heat around the mold 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.
