⭐ Dark Brown Sugar (Best Nut-Free Option)
1:1 (1 cup dark brown sugar per 1 cup brown sugar)Dark brown sugar contains a higher molasses content than light brown sugar, which enhances the caramel and toffee notes crucial for teriyaki sauce’s depth. The moisture content helps maintain the sauce’s viscosity and mouthfeel.
When substituting, use the same volume as brown sugar. Because it is slightly more intense, taste the sauce and adjust if needed. No additional liquid adjustments are typically necessary.
The final sauce will be nearly indistinguishable from the original, preserving the sweet, rich, and slightly smoky profile expected in teriyaki.
