Wow, nice find on my part. I love to grill. Not saying I'm the best at it, but willing to learn.
I have a Weber Genesis grill which I love. The wife is German and thinks my steaks are perfect...and wants me to still use marinade. I usually Jaccard then put steaks in zip locks and add marinade for 1 hour. Then I sear on a 400 deg grill ~ 1-2 min per side, depending on thickness.
I've been trying to use just salt and pepper dry rub. She still likes the marinade. To each their own I guess.
I watched the Douglas Baldwin video and he was searing using a butane torch. Who doesn't like FIRE BABY? Try doing that as the final presentation in front of friends and family. I read that you use a piping hot cast iron pan.
My question is what is the benefit or difference. My thinking is there isn't. A sear = a sear.
That torch was kick ass thou
