Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 400°F (200°C).
Make and shape the dough
In a bowl, mix vinegar, molasses, egg, lard, salt, and baking soda.
Gradually add white flour until the dough is manageable.
Roll out the dough and cut with a cookie cutter.
Bake
Place cookies on a baking sheet and bake carefully.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Molasses
- Adds moisture, deep sweetness and the dark color of the cookies.
- Egg
- Binds the dough and adds structure as the cookies set.
- Lard
- Provides fat for tenderness and a short, crumbly texture.
- Baking soda
- Reacts with the acidic vinegar and molasses to leaven the cookies and aid browning.
- Vinegar
- Acidifies the dough so it reacts with the baking soda to lift the cookies.
- White flour
- Provides the main structure as it is worked into the dough.
The step that matters
Gradually add white flour until the dough is manageable. Adding flour too quickly can make the dough stiff and dense, while too little leaves it sticky and hard to roll. Adding it gradually lets you reach a workable texture without overworking the gluten that makes cookies tough.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
