Why it works: Milk and butter 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 ↓
New England Raised Doughnuts
Ingredients
Directions
Make the dough
Mash the boiled potato smoothly.
Add milk, salt, yeast, and flour to the potato and let rise overnight.
In the morning, stir in sugar, lard, butter, beaten eggs, cinnamon, and baking soda, adding enough flour to make a thick batter.
Let the dough rise until light.
Shape and fry
Roll out the dough to ½ inch thick and let it stand for 15 minutes after cutting into shapes.
Fry in hot oil until golden brown, ensuring they are fully cooked by breaking one open.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the gluten network that traps gas and gives the doughnuts their structure.
- Yeast
- Produces gas as it ferments, causing the dough to rise and become light.
- Eggs
- Add structure and richness, helping the dough set and brown during frying.
- Sugar
- Adds sweetness and helps the doughnuts brown in the hot oil.
- Butter and lard
- Add fat for tenderness and a softer crumb.
- Boiled potato
- Adds moisture and starch that keep the dough soft and help it rise.
The step that matters
Frying until fully cooked. Outside browning happens quickly in hot oil, while the centre needs time to cook through. Breaking one open checks that the interior is done before the rest are removed.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, cinnamon, flour, egg, sugar):

- Chivefits about as well
- Potatothe original
Fit is the average pairing score against milk, butter, cinnamon, flour, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
