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 ↓
Potato Rolls
Ingredients
Directions
Prepare the dough
Boil four large potatoes, then mash them through a colander.
Sift one quart of flour and place it in a bowl.
While the potatoes are still hot, mash them into the flour and work them in with the butter until smooth.
Add the beaten eggs, salt, sugar, and yeast, and knead well on a board.
Let the dough rise until ready for tea (in summer at 12:00, in winter at 11:00).
Shape and bake
About an hour before tea, turn the dough onto a floured board, lightly flour it, and roll it out to half an inch thick.
Cut the dough into round cakes and place them in a pan to rise, ensuring they do not touch.
Bake the rolls for fifteen minutes.
Nutrition, whole recipe (rough)
Counts 5 of 6 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 5 portions
| Ingredient | Portion assumed | kcal |
|---|---|---|
| Flour | 1 cup (125g) all-purpose | 455 |
| Potato | 1 medium (173g) baked | 161 |
| Butter | 1 tbsp (14g) | 102 |
| Egg | 1 large egg (50g) | 78 |
| Salt | 1 tsp (6g) | 0 |
| Coffee | not in our table | 0 |

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
- Flour
- Forms the structure that holds the dough and gives the rolls their body.
- Potatoes
- Add moisture and starch that keep the rolls soft and tender.
- Butter
- Adds fat that softens the crumb and gives a rich texture.
- Eggs
- Add structure and richness, helping the rolls hold together and set when baked.
- Yeast
- Produces gas that makes the dough rise and become light.
The step that matters
Let the dough rise fully before shaping. Yeast needs enough time to produce gas and build the airy structure; rising too briefly leaves the rolls dense, while the dough should be given time in a warm spot to develop properly.
Swap the potato
How well each one fits the dish's main ingredients (flour, butter, egg, coffee):
- Asparagusfits about as well
- Potatothe original
- Arrowrootfits about as well
- Chivefits about as well
Fit is the average pairing score against flour, butter, egg, coffee. Candidates are from the same food group and used in at least 100 recipes.
