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 Gems
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
Preheat the oven to 400°F (200°C).
Make and bake
In a bowl, mix the rye flour, wheat flour, milk, eggs, and salt until smooth.
Pour the batter into gem pans.
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and help the gems set and hold their shape as they bake.
- Wheat flour
- Provides gluten-forming structure so the gems hold together with a lighter crumb than rye alone.
- Rye flour
- Adds flavor and a denser texture to the gems.
- Milk
- Adds moisture and helps the batter bake to a golden brown color.
The step that matters
Bake in the preheated oven until golden brown. The oven must already be hot when the batter goes in, so the batter sets quickly and rises. Starting in a cold oven makes the gems dense and pale. Browning comes from the milk sugars and proteins reacting with heat, so judge by color as well as time.
