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 slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix the oatmeal and flour together.
Rub in the butter lightly.
Add the sugar, spice, and ginger.
Melt the treacle and stir it into the mixture.
Dissolve the baking soda in a little milk and add it to the mixture.
Add more milk if needed to make a soft dough.
Shape and bake
Divide the mixture into small flat cakes.
Brush the cakes with milk.
Place on a greased baking sheet and bake in a slow oven at 300°F (150°C) for about 45 minutes.

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
- Coarse oatmeal
- Forms the bulk of the dough and gives the parkin its hearty, slightly crumbly texture.
- Treacle
- Adds sweetness, dark color, and moisture, helping the cakes stay soft and sticky.
- Butter
- Adds fat that enriches the dough and tenderizes the texture.
- Baking soda
- Reacts with the treacle's acidity to lift the cakes so they rise and stay light.
- Flour
- Adds structure to bind the oatmeal into a dough that holds its shape.
- Ground ginger
- Provides the warm, spicy aroma that characterizes parkin.
The step that matters
Dissolving the baking soda in milk before adding it. Baking soda needs to be fully dissolved so it spreads evenly through the dough; otherwise pockets of soda can leave bitter taste or uneven rising when it reacts with the treacle's acidity.
Swap the ginger
How well each one fits the dish's main ingredients (butter, flour, sugar, milk):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against butter, flour, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
