Why it works: Buttermilk and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

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 help give the cooked pudding its set structure.
- Baking soda
- Reacts with the acidic sour cream and buttermilk to produce gas that lightens the pudding.
- Sour cream
- Adds moisture, richness, and a tangy acidity that activates the baking soda.
- Buttermilk
- Adds moisture and acidity that works with the baking soda to lift the batter.
- Flour
- Provides the structure that holds the thick batter together while it steams.
The step that matters
Gradually add flour until the batter can drop nicely from a spoon. Too much flour makes the pudding dense and heavy, while too little leaves it loose and unable to hold its shape. Adding it gradually lets you stop at the right thickness.
Swap the nuts
The recipe marks nuts as optional. How well each one fits the dish's main ingredients (cream, buttermilk, egg, flour):
- Almondfits better
- Hazelnutfits better
- Pistachiofits better
- Nutsthe original
Fit is the average pairing score against cream, buttermilk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
