Why it works: Milk and butter 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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Dissolve the baking soda in the warm milk.
Add the salt and beaten eggs to the milk mixture.
Stir in enough rye flour to create a thin batter.
Bake and serve
Grease small cups with butter and fill them with the batter.
Bake in a hot oven at 400°F (200°C) or pour small amounts onto a hot griddle.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as the cakes set.
- Baking soda
- Reacts with the milk to produce gas that helps the cakes rise.
- Rye flour
- Forms the body of the batter and gives the cakes their structure and earthy flavour.
- Milk
- Hydrates the flour and provides moisture so the batter pours thinly.
The step that matters
Keep the batter thin and pour into a hot pan or oven. A thin batter spreads and rises evenly, while a hot cup, oven or griddle sets the outside quickly so the cakes lift instead of turning dense and flat.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
