When almost ready to serve: If there is any condensation on the top of custards, gently dab with a paper towel to dry. Transfer custards to freezer and freeze for 15 minutes. Arrange oven rack right under broiler. Preheat broiler to high. After freezing, place custards on a sheet pan and sprinkle 1 tablespoon sugar over each custard. Make sure sugar is in an even layer. Broil for 4-5 minutes, rotating as needed so they broil evenly. Watch closely the whole time. (If this is your first time making creme brulee, you may want to broil just 1 at a time to get the hang of it.) With an electric oven, you may need to crack the door open so the coil stays on (glowing orange). I found when the coil turned off, the sugar did not brown. Remove from oven when the sugar turns brown. Holding the ramekin with oven gloves, tilt it back and forth while the melted sugar is still liquid to help evenly distribute.
