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 ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Mix the dough
Sift together the tartaric acid, bicarbonate of soda, and flour.
Work the butter into the flour mixture.
Add the sugar, currants, and caraway seeds, mixing well.
Make a well in the center and pour in the milk mixed with the beaten egg.
Mix quickly and drop spoonfuls of dough onto baking tins.
Bake
Bake for about 20 minutes at 400°F (200°C).
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.

Flour and butter 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
- Tartaric acid
- Reacts with the bicarbonate of soda to release carbon dioxide, which lifts the buns.
- Bicarbonate of soda
- Releases carbon dioxide when combined with the acid, leavening the buns for a light texture.
- Flour
- Provides the structure that sets around the expanding gas as the buns bake.
- Butter
- Adds fat that tenderizes the crumb and gives a softer bite.
- Egg
- Adds structure and richness, helping bind the dough.
- Milk
- Supplies moisture that hydrates the flour and activates the leavening.
The step that matters
Mix quickly and drop the dough. Tartaric acid and bicarbonate of soda start releasing carbon dioxide as soon as they meet liquid. Delaying the mixing and shaping lets much of that gas escape, so the buns may bake up flatter and denser.
Swap the caraway
The recipe marks caraway as optional. How well each one fits the dish's main ingredients (flour, butter, sugar, currant, milk, egg):
- Cinnamonfits better
- Nutmegfits better
- Carawaythe original
- Allspicefits about as well
Fit is the average pairing score against flour, butter, sugar, currant, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
