Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Sweet Potato Cakes — Very Nice
Ingredients
Directions
Prepare the dough
Remove the skin from the sweet potatoes and mash them well.
Mix in the flour, salt, pepper, and butter.
Add enough warm milk to form a good dough.
Roll out the dough on a floured surface and cut into cakes the size of your baking tin.
Bake
Butter the baking tin and sprinkle a little flour over it.
Place the cakes in the tin and bake until nearly done, then turn them over.
If the bottom of the oven is very hot, place a grate under the baking tin.

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
- Sweet potatoes
- Provide the bulk and moisture of the dough, along with a soft, starchy body.
- Flour
- Absorbs moisture and gives the mashed potato mixture enough structure to hold its shape.
- Butter
- Adds fat for richness and a tender texture, and helps the cakes brown in the tin.
- Milk
- Hydrates the mixture so it comes together into a workable dough.
The step that matters
Turning the cakes. Turning them only once they are nearly done lets the first side set and firm up so it does not break, while the second side finishes and browns evenly.
Swap the sweet potato
How well each one fits the dish's main ingredients (flour, pepper, butter, milk):
- Potatofits better
- Capsicumfits better
- Chivefits about as well
- Sweet potatothe original
Fit is the average pairing score against flour, pepper, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
