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 ↓

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.
Make the dough
Warm the milk and butter together.
Add enough flour to create a soft sponge, then mix in the yeast and salt.
Let the mixture rise, then work in the mashed potatoes and add more flour until a nice dough forms, slightly softer than bread dough.
Allow the dough to rise again.
Shape and bake
One hour before baking, roll out the dough, cut it into shapes, place in pans, and bake at 400°F (200°C).
For breakfast, prepare the dough the night before and work with it first thing in the morning.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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
- Builds the structure of the dough as its proteins form gluten and absorb liquid.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Butter
- Adds fat that tenderises the crumb and gives a rich flavour.
- Milk
- Supplies moisture that hydrates the flour and softens the dough.
- Potatoes
- Add moisture and starch that keep the biscuits soft and tender.
The step that matters
Adding flour until the dough is right. Flour must be added gradually until the dough is soft but not sticky. Too little leaves it wet and collapsing, while too much makes the biscuits dense and dry.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, flour):
- Potatothe original
- Arrowrootfits about as well
- Leekfits less well
- Shallotfits less well
Fit is the average pairing score against milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
