Dark Corn Syrup (Best Option)
1:1 by volumeDark corn syrup contains glucose and molasses, which mimic the moisture and caramelized flavor of brown sugar, essential for the custard soak in French Toast. This helps the bread absorb the custard evenly without becoming overly soggy.
When using dark corn syrup, reduce other liquids slightly to compensate for its moisture content. Stir it well into the custard to ensure even distribution.
The final French Toast will have a close approximation to the original sweetness and texture, with a slightly smoother mouthfeel due to the syrup’s liquid form.
