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 ↓
Hard Cookies
Ingredients
Directions
In a large bowl, cream together the sugar and butter.
Gradually add the flour and enough water to form a dough.
Knead the dough for a long time, then let it rest for 1-2 hours.
Knead the dough again, then roll it out thin.
If desired, sprinkle in caraway seeds.
Cut the rolled dough into small cakes.
Stamp each cake with a wooden print.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Swap the caraway
The recipe marks caraway as optional. How well each one fits the dish's main ingredients (sugar, butter, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits about as well
- Carawaythe original
Fit is the average pairing score against sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
