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 ↓
Old Fashioned Rusk
Ingredients
Directions
Make the sponge
Dissolve a cake of compressed yeast in a gill of warm water.
Sift a pint of flour into a large bowl.
Add a teaspoon of salt and a pint of warm milk. Stir well and add the melted yeast cake.
Cover and set in a warm place overnight.
Shape the rusks
In the morning beat a half cupful of butter, one cup granulated sugar, and three eggs into a cream. Stir this mixture into the sponge.
Sift in enough flour to make a soft dough.
Put the dough on a floured board and roll it to a thickness of half an inch. Cut out with a small biscuit cutter.
Place the biscuits in a baking pan greased with lard. Cover and let rise until spongy and light.
Bake and serve
Bake in a moderate oven for about twenty-five minutes.
When removed from the oven, brush tops with a roll of paper dipped in milk. Sprinkle powdered sugar over them.
Serve hot.
Nutrition, whole recipe (rough)
Counts 8 of 10 ingredients. The other 2 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 8 portions

| Milk | 1 cup (244ml) whole | 149 |
| Lard | 1 tbsp (12.8g) | 115 |
| Butter | 1 tbsp (14g) | 102 |
| Egg | 1 large egg (50g) | 78 |

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
- Yeast (in the method)
- Ferments the sponge, producing gas that makes the dough rise and turn light.
- Flour
- Forms the gluten network that gives the dough its structure.
- Eggs
- Add richness and structure, helping the dough set and hold its shape.
- Butter
- Adds fat, giving the dough tenderness and a richer flavour.
- Sugar
- Sweetens the dough and helps browning on the baked tops.
The step that matters
Let the shaped rusks rise until spongy and light. Yeast needs time and warmth to produce gas; under-proofed rusks stay dense, while the rise sets the light texture before baking.
Swap the lemon

Fit is the average pairing score against butter, sugar, flour, corn, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
