This process can be done with a stove top and oven or side burner and grill. You need the burner to heat the skillet and start the steak cooking. You need the grill or oven to finish it off. Either way you go the grill or oven needs to be preheated to a high temperature. I shoot for around 500 degrees F. (260 degrees C.), but any temperature around 400 degrees F. (205 degrees C.) or higher will do.
This process creates a good deal of smoke. You won't notice it much on the patio, but your fire alarm probably will notice if you choose to do this indoors. If you are doing this in the kitchen you might want to turn off the fire alarm for the duration.
