Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Hard Gingerbread
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a bowl, combine molasses, shortening, sour milk, baking soda, and spices.
Gradually add flour until the mixture is very soft.
Shape and bake
Shape the dough into a cake about 2 inches thick.
Bake in a slow oven at 300°F (150°C) until firm.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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 dark sweetness, moisture, and the characteristic flavor and color of the gingerbread.
- Shortening
- Adds fat, which tenderizes the crumb and carries the spices.
- Sour milk
- Its acidity reacts with the baking soda and adds moisture to the dough.
- Baking soda
- Reacts with the acid in the sour milk and molasses to release gas, helping the dough rise.
- Flour
- Provides structure, setting the dough as it bakes until firm.
The step that matters
Adding the flour gradually. Flour should be added little by little until the dough is very soft. Adding too much at once or too much overall can make the gingerbread dense and hard to shape, while stopping too early leaves it too wet to hold a cake shape.
“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.
