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

  1. Preheat your oven to 350°F (175°C).

Mix and shape

  1. In a bowl, mix the sour milk, flour, sugar, rye meal, baking soda, and salt until well combined.

  2. Shape the dough into rolls and place them on a baking sheet.

Bake

  1. Bake for 15-20 minutes or until golden brown.

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.
