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 Shortcake
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
Sift the rye flour with the sugar.
Sift the wheat flour with the cream of tartar.
Dissolve the baking soda in the sweet milk.
Fill a tumbler with sour milk.
Make the batter
Stir the sour milk and sour cream gradually into the flour mixture.
Add the beaten eggs. Mix well.
Bake
Preheat a gem roll pan on the stove.
Grease it with butter.
Fill the pan nearly full.
Bake in a hot oven at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye flour
- Gives the shortcake a tender, slightly earthy crumb with less gluten structure than wheat flour.
- Wheat flour
- Provides gluten structure so the shortcake holds its shape while it bakes.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Sour milk
- Its acidity reacts with the baking soda to produce gas, lifting the batter.
- Sour cream
- Adds fat and moisture, producing a softer, richer crumb.
- Baking soda
- Reacts with the acidic sour milk and cream of tartar to leaven the batter.
The step that matters
Stir the sour milk and sour cream gradually into the flour mixture. Baking soda starts reacting as soon as it meets acid, so the batter should be mixed gently and baked promptly to keep the gas bubbles that make the shortcake rise.
