How can I use a torch for searing steak to achieve the perfect crust and flavor?

To achieve the perfect crust and flavor when searing steak with a torch, hold the torch about 2-3 inches away from the steak and move it in a circular motion to evenly sear the surface. Make sure to keep the torch moving to prevent burning. Sear each side for about 30 seconds to 1 minute, depending on the thickness of the steak. This will create a caramelized crust and enhance the flavor of the steak.
