sirloin Recipe

reubeny,
i am a caterer and have cooked many a sirlion.
the best way that i have found is to clean the meat of as much back fat as you want ( I completly strip it)
then season it and seal it well on a HOT grill.
top with what ever you want (mustards , fresh herbs, toasted crumbs , brioche crumbs ect )and cook in a hot over 180 (350 ) for aprox 20 to 30 minutes (convection oven) or 30 to 50 minutes for a still oven.
the key to this is to check its progress
at the latter stages , but most of all to let it rest ofter you take it out for a good 15 minutes. This ollows a the juices to be drawn back in and peeks the meat nice and juicy
I allow 20 serves to the full sirloin(caterers portion)
hope this helps
any mors questions and i will be happy to help if i can

as above
