Dark Corn Syrup (Best Option)
1:1 by volume (e.g., 1 tablespoon dark corn syrup per 1 tablespoon brown sugar)Dark corn syrup contains glucose and maltose, which provide fermentable sugars similar to brown sugar, supporting yeast activity without overwhelming the sourdough culture. Its molasses content mimics the flavor profile of brown sugar, enhancing the bread's complexity.
When substituting, reduce other liquid components slightly to compensate for the syrup's moisture. Mix thoroughly to ensure even distribution and avoid overly sticky dough.
The final bread will have a similar moist crumb and subtle sweetness, maintaining the characteristic sourdough tang with enhanced caramel notes.
