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).
In a bowl, combine rye flour, wheat flour, and coarse sea salt.
In another bowl, mix sour milk and baking soda; let it foam.
Mix and bake
Stir the foaming mixture into the flour mixture along with molasses.
Mix until stiff, then transfer to a buttered pan.
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 a dense, moist crumb with less gluten structure than wheat flour.
- Wheat flour
- Adds gluten for some structure and a lighter crumb than rye alone.
- Sour milk
- Supplies liquid and acidity that reacts with the baking soda.
- Baking soda
- Reacts with the acidic sour milk to release gas that lifts the cake.
- Molasses
- Adds sweetness, moisture, and a dark color and deep flavor.
The step that matters
Let the sour milk and baking soda foam before mixing. The acid-base reaction releases carbon dioxide bubbles that give the cake its lift. Waiting for the foam to form before combining ensures the leavening is active in the batter.
