After your 30 minutes are up, turn on your oven to 400 degrees F.
While your oven is heating, take off the damp cloth. It’s time to score those buns!
Traditionally to do this, people use a lame. If you don’t have one, a good substitute is simply a clean razor or a sharp knife. If you’d like to get one, here’s the one I use, it comes with a handle that sometimes I use, and 5 blades.
When scoring the buns, be careful not to deflate them by using too much pressure.
I like to score the buns in a square shape. This helps create an easy opening for when it’s time to cut them open.
