Controlling overnight fermentation

This recipe creates a lightly tangy dough. To control how quickly our dough ferments (hence acid development), we will be using a small amount of starter and cold ingredients. The result is a lightly tangy dough that just brings that “extra something” to the traditional sweet rolls.

  • Use cold ingredients: Using cold ingredients, like milk and eggs, slows down the fermentation process, reducing the production of lactic acid during the 8-10 hour rise.
  • Salt & Sugar: You have heard people say “salt kills yeast”. In truth, salt does NOT kill yeast, but it plays a role in slowing down the activity of yeast. Same with sugar, above a certain percentage (roughly 5%), it will slow down fermentation. Why? Sugar and salt both draws water away from the yeast, resulting is slower fermentation. You can read more about it here.
  • Fat: Milk, eggs and butter adds a richness to the dough which inhibits gluten formation and surrounds the yeast with fat, resulting in slower fermentation.
  • Overnight rise: Temperatures are cooler at night and as a result, it moderates the speed of fermentation
