Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Sour Milk Doughnuts
Ingredients
Directions
Make the dough
In a bowl, beat the eggs and mix in the sugar and butter until smooth.
Stir in the sour cream or milk, baking soda, salt, and nutmeg.
Gradually add flour until a stiff dough forms.
Cover the dough and refrigerate overnight.
Shape and fry
The next morning, let the dough sit in a warm place for 2 hours.
Roll out the dough and cut with a doughnut cutter.
Fry the doughnuts in deep hot oil until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add richness and structure to the crumb.
- Sugar
- Sweetens the doughnuts and helps them brown when fried.
- Butter
- Adds fat for tenderness and flavour in the dough.
- Sour cream or milk
- Supplies moisture and acidity that reacts with the baking soda.
- Baking soda
- Reacts with the acidic dairy to produce gas that helps the doughnuts rise.
- Flour
- Forms the gluten and starch structure that holds the stiff dough together.
The step that matters
Gradually add flour until a stiff dough forms. Adding flour slowly lets you stop at the right stiffness. Too much flour makes the doughnuts dense and tough, while too little leaves a dough too soft to roll and cut cleanly.
