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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a bowl, mix the flour, baking soda, cream of tartar, butter, and salt.
Add sweet milk gradually until a soft dough forms.
Drop spoonfuls of the mixture onto a baking sheet.
Bake
Bake in the preheated oven until golden brown.

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
- All-purpose flour
- Provides the starch and gluten network that gives the rolls their structure.
- Baking soda
- Reacts with the acid in cream of tartar to release gas, helping the rolls rise.
- Cream of tartar
- Supplies acid that reacts with baking soda, producing lift and a tender crumb.
- Butter
- Adds fat that tenderizes the crumb and contributes flavor and browning.
- Sweet milk
- Hydrates the flour into a soft dough and adds moisture to the crumb.
The step that matters
Add sweet milk gradually until a soft dough forms. Too much milk makes the dough slack and spreads it on the sheet, while too little leaves dry, dense rolls. Adding it slowly lets you stop at a soft, scoopable consistency.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
