Cooking Broccoli: High Heat, No Water

with chicken and cheddar

I found this here: http://www.thewednesdaychef.com/the_wednesday_chef/2008/08/heston-blumenth.html
and it's my new favourite way to cook broccoli. Quick, easy, great results.

I use a cast iron frying pan. Basically:
v high heat, add some olive oil [smokin' hot]
broccoli in, lid on, don't touch it for 2 minutes
after two minutes: salt & pepper, some butter, shake it all about, lid back on, still high heat, don't touch it for 2 minutes
is it done? if not, leave it on another minute or two, otherwise it's ready to eat
