Why it works: Butter and milk 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 ↓
Lepp Kuchen or German Cookies
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 dough
Cream butter, lard, whiskey, and salt together.
Add spices, chopped nuts, and anise seed, then mix in flour to form a stiff dough.
Let dough stand overnight.
Shape and bake
Roll out dough and cut into desired shapes.
Bake at 350°F (175°C) until golden.
Brush cookies with sweet milk and sprinkle sugar before baking for a lighter texture.
Optionally spread beaten egg white on top and sprinkle sugar for decoration.

Butter and flour 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
- Butter
- Adds richness and a tender crumb through its fat and flavor.
- Lard
- Shortens the dough, giving a tender, crisp texture.
- All-purpose flour
- Forms the gluten network that gives the stiff dough its structure.
- Chopped nuts
- Add texture and a toasty, rich flavor to the cookies.
- Anise seed
- Contributes a distinctive licorice-like aroma.
The step that matters
Let the dough stand overnight. Resting lets the flour fully hydrate and the fats firm up, which makes the stiff dough easier to roll evenly and helps the cut shapes hold their form in the oven.
Swap the anise
How well each one fits the dish's main ingredients (butter, nuts, flour, milk, sugar, egg):
- Cinnamonfits better
- Nutmegfits better
- Capersfits better
- Anisethe original
Fit is the average pairing score against butter, nuts, flour, milk, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
