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 ↓

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
Rub the sugar and eggs together until well combined.
Add the milk and ammonia, then mix in the flour.
Bake
Drop spoonfuls of the mixture, the size of a small egg, onto greased and floured pans.
Bake in a hot oven at 400°F (200°C) until golden.

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
- Eggs
- Provide structure and lift as they set in the oven, giving the drops their body.
- Flour
- Forms the starch and protein framework that holds the drops together as they bake.
- Milk
- Adds moisture and liquid that turns the mixture into a loose batter and aids browning.
- Sugar
- Adds sweetness and promotes golden browning on the surface of the drops.
The step that matters
Bake in a hot oven until golden. The batter is loose, so the drops must set quickly in a hot oven. The heat coagulates the eggs and gelatinizes the starch before the mixture can spread, and browning shows the surface has set.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, milk, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
