Flat Iron love a challenge. They also love great beef, so when they had the idea of roasting a whole cow 'hog roast' style, and the gang at The Ship in Wandsworth said they would be up for hosting, they couldn't really not do it.
Turns out when you move from pigs (50kg) to cattle (280kg) you have to beef things up a bit. 40 hrs cooking, yep, 7 ton of sustainably sourced hardwood, yep, custom welded steel spit with 2 five foot cartwheels. It hasn't been done in 30 yrs but they managed it. We were pretty impressed. see the video below.
