Why it works: Flour and caraway match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,435 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Luncheon 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).
Make the batter
In a large bowl, cream the butter and sugar together.
Add the eggs and milk, mixing well.
In another bowl, combine the flour, caraway seeds, currants, candied peel, and baking soda.
Gradually add the dry ingredients to the wet mixture, stirring until combined.
Pour the batter into a greased baking pan.
Bake
Bake for 1 to 1.5 hours or until a toothpick comes out clean.

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
- Creamed with sugar to trap air and add richness and tender crumb.
- All-purpose flour
- Provides the main structure as its proteins set during baking.
- Eggs
- Bind the batter and add structure and richness as they set.
- Moist sugar
- Adds sweetness, moisture and a soft, tender texture.
- Baking soda
- Reacts with the batter's ingredients to produce gas that helps the cake rise.
- Milk
- Adds moisture and helps form a smooth, pourable batter.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in portions and stirring just until combined keeps the batter smooth and limits gluten development, which would otherwise make the cake tough.
