These Sourdough Ube Sweet Rolls are soft, nutty and sweet. The ube halaya filling keeps the dough soft and tender and the cookie crumble on top adds a textural contrast. It is super easy to make and best part? You mix the dough the night before and you’ll have soft rolls ready in the morning!
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
