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 ↓
Sally-lunn, with Yeast
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 batter
Dissolve the butter in the warmed milk.
Beat the yolks of the eggs well and add to the milk and butter mixture.
Stir in the sugar and yeast.
Gradually mix in the sifted flour.
Whip the egg whites until stiff and fold them into the batter.
Let the batter rise in a warm place until doubled in size.
Shape and bake
Beat the batter again and pour it into greased pans about 1 inch deep.
Allow to rise a second time in a warm place.
Bake in a preheated oven at 400°F (200°C) until light and golden.

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
- Butter
- Adds richness and tenderness, softening the crumb and carrying flavour.
- Eggs
- Egg whites whipped to stiffness lighten the batter, while yolks add richness and structure.
- Yeast
- Ferments the sugars and produces gas that makes the batter rise and turn airy.
- Flour
- Forms the gluten network that gives the bread its structure once baked.
- Sweet milk
- Hydrates the flour to form the dough and adds moisture and softness.
- Granulated sugar
- Feeds the yeast and adds sweetness and gentle browning to the crust.
The step that matters
Let the batter rise until doubled. Yeast needs a warm, adequate rise to build gas and air cells; under-proofing leaves a dense loaf, while the second rise must also be allowed to finish before baking so the crumb stays light.
