In the meantime, preheat the oven to 425 F.
Once the rolls come out of the baking soda bath, bake them for 10 to 15 minutes or until the top is dark brown and the rolls sound hollow when tapped at the bottom. It took me about 12 minutes.
I had placed two trays in the oven and I switched the position of both the trays once in between to ensure even browning.
Once the rolls come out of the oven, cool them on a rack and serve warm or at room temperature.
Never store these rolls covered or in a box as they tend to become soggy. Leftover rolls can be stored uncovered in room temperature for 2 to 3 days.
