Why it works: Wheat and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,373 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make and dry the cakes
Mix cornmeal, wheat flour, molasses, salt, and enough water to form a stiff dough.
Roll the dough thin and cut out shapes like yeast cakes.
Place the cakes in a pan.
Dry the cakes in a 400°F (200°C) oven.
Wait until the cakes are thoroughly dry.
Brown the cakes very dark.
Brew and serve
To use, place 2 or 3 dried cakes and 1 tablespoon of coffee in a pot.
Pour boiling water over the cakes.
Let the mixture boil.
Allow it to settle.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornmeal
- Provides the bulk and coarse, sandy texture of the dough.
- Wheat flour
- Gives the dough structure so it holds its cut shapes.
- Molasses
- Adds sweetness and moisture, and deepens the dark color when the cakes are browned.
- Dried cakes
- Once browned, they contribute roasted flavor to the brewed drink.
- Coffee
- Adds its own aroma and bitterness to the brew.
The step that matters
Dry the cakes thoroughly before browning. Cakes that still hold moisture stay soft and brown unevenly, while fully dried cakes can roast evenly and keep well for later use.
