Why it works: Flour and rye 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 Rolls
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Mix and shape
In a bowl, mix the sour milk, flour, sugar, rye meal, baking soda, and salt until well combined.
Shape the dough into rolls and place them on a baking sheet.
Bake
Bake for 15-20 minutes or until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Provides moisture and acidity that reacts with the baking soda to help the rolls rise.
- Flour
- Provides the main structure that holds the rolls together.
- Rye meal
- Adds its distinctive flavour and a denser, heartier texture.
- Baking soda
- Reacts with the acid in the sour milk to produce gas that lifts the dough.
- Sugar
- Adds sweetness and helps the rolls brown in the oven.
The step that matters
Mixing the dough and baking soon after. Baking soda starts reacting as soon as it meets the acid in the sour milk. Shaping and placing the rolls in the oven promptly keeps the gas produced in the dough so the rolls rise well.
