Why it works: Rye and wheat match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 404 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Rye Cakes for Tea
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, combine rye flour, wheat flour, and salt.
In another bowl, mix sour milk and baking soda until foamy.
Stir the foamy mixture into the flour mixture.
Add molasses and mix until stiff.
Bake
Transfer the batter to a buttered pan and smooth the top with a spoon dipped in hot water.
Bake for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye flour
- Forms the dense, sturdy crumb that gives this cake its character.
- Wheat flour
- Adds gluten structure so the cake holds together better than rye alone.
- Sour milk
- Its acidity reacts with baking soda to produce gas that lifts the batter.
- Baking soda
- Reacts with the acidic sour milk to release carbon dioxide for rising.
- Molasses
- Adds sweetness, moisture and a deep, dark color to the cake.
The step that matters
Mixing the foamy milk and baking soda into the flour. The soda must be activated by the acid in the sour milk while the mixture is foamy, and the batter should be stirred only until combined. Overmixing develops gluten and can make the crumb tough, while delaying the bake lets the rising gas escape.
