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 the dough
Melt the butter and stir it into the oatmeal with a spoon.
Add brown sugar and treacle to make the mixture moist.
In a separate bowl, mix yeast and sugar with warm milk.
Add the milk mixture to the oatmeal mixture and stir in the egg.
Knead lightly and cut the dough into two pieces.
Rise and bake
Place in tins and cover for 1 hour in a warm place.
Bake in a preheated oven at 400°F (200°C) for 15 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Forms the bulk of the dough and gives the parkin its hearty, crumbly body.
- Butter
- Adds fat for richness and a tender texture as it coats the oats.
- Treacle
- Adds moisture, sweetness and a dark color that helps the parkin brown.
- Brown sugar
- Adds sweetness and moisture, and helps the crust brown during baking.
- German yeast
- Ferments slowly in the warm rest, producing gas that lifts the dough.
- Egg
- Binds the mixture together and adds structure and richness.
The step that matters
Leaving the dough to rise in a warm place. Yeast needs warmth and time to produce gas. If the dough is cold or rises too briefly, it stays dense; if it is left too long in heat, it can over-proof and collapse.
Swap the ginger
How well each one fits the dish's main ingredients (butter, sugar, egg, milk):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Parsleyfits about as well
Fit is the average pairing score against butter, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
