Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. 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 the dough
Preheat the oven to 400°F (200°C).
In a bowl, cream together the butter, egg, brown sugar, and black molasses.
Dissolve the Magic Soda in boiling water and add to the mixture.
Gradually add flour to form a soft dough.
Shape and bake
Roll the dough thin and cut with a cookie cutter.
Bake until cooked, then while hot, spread jelly on one cookie and stick another on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, helping the cookies stay soft and flavourful.
- Egg
- Binds the dough and adds structure as the cookies set.
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown.
- Black molasses
- Adds dark colour, moisture and a deep, slightly bitter sweetness.
- Magic soda
- Reacts with the molasses to lift the dough so the cookies rise and soften.
- Flour
- Provides the structure that holds the dough together and sets when baked.
The step that matters
Dissolving the Magic Soda in boiling water. The soda must be fully dissolved and mixed in evenly so it reacts with the acidic molasses throughout the dough. Uneven mixing leaves pockets of soda that can taste bitter or cause uneven rising and colour.
