Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Yolks enrich the batter and whites, folded in, give the pudding its light, airy structure.
- Flour
- Provides starch that sets during baking and gives the pudding its body.
- Potato flour
- Adds starch that sets during baking, giving a tender, delicate crumb.
- Fresh butter
- Adds richness and fat, making the icing smooth and creamy.
- Powdered white sugar
- Sweetens the batter and icing and helps the icing hold a smooth texture.
The step that matters
Gently fold in the beaten egg whites. Whites hold air that gives the pudding its lift. Stirring or deflating them vigorously knocks out the air, leaving a dense, flat result.
Swap the potato
How well each one fits the dish's main ingredients (sugar, egg, flour, butter, coffee):
- Arrowrootfits about as well
- Sweet potatofits about as well
- Asparagusfits about as well
- Potatothe original
Fit is the average pairing score against sugar, egg, flour, butter, coffee. Candidates are from the same food group and used in at least 100 recipes.
