I have a question about step 7 on the recipe "Crusty Dinner Rolls" from wssmom. It says:
"Brush tops of rolls with the cornstarch mixture. Using a sharp serrated knife, make a half-inch deep slash lengthwise across the top of each rolls. Bake at 375 degrees for 25 to 30 minutes." How much should I reduce the baking time if I make the rolls smaller?
