Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Directions
The book says “a fairly brisk oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Beat in the eggs one at a time.
Mix the flour and ground rice together.
Gradually beat it into the mixture.
Bake
Line a baking tin with buttered paper.
Pour the mixture into the tin.
Bake at 350°F (175°C) for about one hour.

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
- Creams with sugar to trap air and give a rich, tender crumb.
- Eggs
- Add structure and richness, setting the cake as they cook.
- Ground rice
- Gives the cake a fine, slightly crumbly and tender texture.
- Flour
- Provides the main structure so the cake holds its shape.
- Castor sugar
- Sweetens the cake and helps trap air when creamed with butter.
The step that matters
Gradually beat in the flour and ground rice. Adding the dry mixture slowly and mixing gently keeps the batter light. Overbeating after the flour goes in develops gluten, which can make the cake tough and dense.
