Why it works: Flour and butter 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 ↓
German Pound Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Line a cake tin with buttered paper, placing three rounds at the bottom.
Make the batter
Beat the butter and sugar together until creamy.
Add the eggs one at a time, beating each in thoroughly.
Gently stir in the sifted flour.
Add the sultanas, chopped candied peel, and grated lemon rind; mix well.
Bake and cool
Pour the batter into the tin and bake for 2 hours.
Once baked, turn the cake out onto a sieve to cool.

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 gives the cake a rich, tender crumb.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Flour
- Forms the cake's main structure once baked.
- Castor sugar
- Sweetens the cake and helps create a light texture when creamed with butter.
- Sultanas
- Add moisture and sweetness, becoming plump within the crumb.
- Baking powder
- Releases gas in the batter to help the cake rise.
The step that matters
Adding the eggs one at a time. Each egg must be beaten in fully before the next is added. Adding them too quickly can cause the butter and sugar mixture to separate or curdle, which can make the finished cake coarse and uneven.
