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 ↓
Old-fashioned Flapjacks
Ingredients
Directions
Make the batter
In a bowl, combine sour milk, cream or butter, egg, and baking soda.
Add flour until the batter is thick enough to drop from a spoon.
Cook and stack
Heat a skillet and pour in batter to form cakes the size of tea plates and ½ inch thick.
Fry until golden brown on both sides.
Spread melted butter on each flapjack, sprinkle with sugar and nutmeg, and layer with dried apples if desired.
Continue stacking flapjacks until all batter is used.
Cut into pie-shaped wedges to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with baking soda to produce gas that lifts the batter.
- Baking soda
- Reacts with the acid in sour milk to leaven the flapjacks so they rise and turn light.
- Egg
- Binds the batter and adds structure so the cakes hold together when flipped.
- Flour
- Provides the starch and protein that set the batter into sturdy, cooked cakes.
- Butter
- Adds richness and helps the outside brown in the skillet and flavours the stacked cakes.
The step that matters
Fry until golden brown on both sides. The batter must be cooked through as well as browned. Over-high heat browns the outside before the centre sets, leaving raw batter inside, while the leavening gas is released by heat and is best trapped while the batter is still being cooked evenly.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (milk, cream, egg, flour, butter, sugar, nutmeg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against milk, cream, egg, flour, butter, sugar, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
