DH said he really enjoyed this as he was eating his 2nd ear of corn! Very easy to prepare. I didn't have time to let the butter sit for 1 hour but it was on the corn about 20 minutes before going on the grill. Enjoyable nonetheless.
I loved the flavor the majoram added to the corn. I didn't have any rosemary, so I skipped that.
So, I thought I'd adapt this a bit and roasted it in the oven. I used no oil/butter and wrapped each ear in foil with a small sprig each of fresh rosemary and oregano. I was using the oven at 325° and the corn roasted for 30 minutes (because I forgot to put it in until it was too late). Not nearly long enough or hot enough and the rosemary was overwhelming. I'd recommend following the recipe or make adjustments accordingly.
I do mine over charcoal and it takes about 20 minutes. I remove the husk completely and then wrap with foil. Much, much better than boiled corn! I have never had better corn on the cob. I usually prepare mine early in the day and then they are ready to pop on the grill at supper time.
