Why it works: Rye and flour match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,320 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rye Biscuits
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make and bake
In a large bowl, mix the rye meal, flour, molasses, egg, salt, sour milk, and baking soda until well combined.
Drop spoonfuls of the mixture onto a greased baking sheet.
Bake for 15-20 minutes or until golden brown.
Serve
Let cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye meal
- Gives the biscuits their dense, hearty texture and a distinctive earthy flavour.
- All-purpose flour
- Provides gluten structure so the biscuits hold their shape while baking.
- Molasses
- Adds sweetness and depth, and contributes to the browning of the crust.
- Egg
- Binds the dough and adds structure and richness.
- Sour milk
- Adds moisture and acidity that reacts with the baking soda.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce carbon dioxide, helping the biscuits rise.
The step that matters
Baking until golden brown. Baking soda reacts quickly with the acidic sour milk, so the batter should go into the oven promptly once mixed. Pulling the biscuits when golden brown, rather than earlier, lets the starches set and the crust form so they hold their shape.
