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 ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
In a bowl, combine rye flour, wheat flour, sugar, and salt.
Beat the eggs until very light, then add the milk.
Pour three‑quarters of the egg and milk mixture into the bowl and beat well.
Add the remaining egg and milk mixture and mix until combined.
Bake
Butter twelve small stone molds and place them in a baking pan.
Bake in a very hot oven at 400 °F (200 °C) for the first 30 minutes.
Reduce the temperature to 350 °F (175 °C) and bake for an additional 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and lift as their proteins set around the steam during baking.
- Milk
- Supplies liquid that turns to steam, helping the batter puff and giving a tender interior.
- Rye flour
- Adds flavor and a lighter structure, while gluten from the wheat flour gives the batter its main framework.
- Wheat flour
- Its gluten forms the network that holds the rising batter in shape.
The step that matters
Beat the batter well and keep the oven hot at the start. Beating develops gluten so the batter can stretch, and a very hot oven makes the steam expand quickly before the set structure forms. Opening the oven early or a weak oven causes popovers to collapse.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
