Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Boston Breakfast Cakes
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Mix the milk, sugar, yeast, eggs, salt, and enough flour to form a thick batter.
Cover and let the batter sit overnight.
If the batter turns sour, add 1 teaspoon of baking soda dissolved in a little milk.
Shape and bake
In the morning, shape the batter into cakes.
Bake the cakes in tins at 350°F (175°C) for about 1 hour.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Yeast
- Ferments the batter overnight, producing gas that makes the cakes rise and turn light.
- Eggs
- Add structure and richness, helping the batter hold its shape while baking.
- Flour
- Forms the gluten network that gives the batter body and the baked cakes their structure.
- Milk
- Hydrates the flour and adds moisture and tenderness to the cakes.
- Baking soda (in the method)
- Neutralises the acid from a sour batter, so it can still rise and bake well.
The step that matters
Letting the batter sit overnight. Yeast needs time to ferment the batter; too short a rest leaves the cakes dense, while a long rest can turn the batter sour, which is why the baking soda correction exists.
