Why it works: Ginger and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,620 recipes. Both carry estragole, which smells anise, licorice. The science ↓
A Commoner Gingerbread
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make and bake the dough
In a bowl, combine the flour, treacle, ground ginger, caraway seeds, and allspice.
Dissolve the pearlash and alum in the milk, then add to the mixture.
Mix all ingredients together to form a paste.
Pour the mixture into a baking pan and bake in the hot oven until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the main structure of the paste as it sets in the oven.
- Treacle (molasses)
- Adds moisture, sweetness, and deep color to the gingerbread.
- Pearlash (potassium carbonate)
- Alkaline leavening agent that reacts with the treacle to help the gingerbread rise and darken.
- Alum
- Acidic salt that works with pearlash to aid rising and texture.
The step that matters
Dissolving the pearlash and alum in the milk. Pearlash and alum react with acids and alkalis in the treacle to produce gas that lifts the dough. They must be fully dissolved and evenly distributed so the rise is uniform and no pockets of harsh alkali remain.
Swap the caraway
The recipe marks caraway as optional. How well each one fits the dish's main ingredients (flour, molasses, ginger, allspice, milk):
- Cinnamonfits better
- Clovefits better
- Cardamomfits better
- Carawaythe original
Fit is the average pairing score against flour, molasses, ginger, allspice, milk. Candidates are from the same food group and used in at least 100 recipes.
