Hi All ~ I am catering a small dinner party Friday. Client's favorite dish is Beouf Bourguignon and I have a fabulous London Broil Top Round for the amount of people. I have used chuck and other beef selections so I wanted to find out if this will have enough fat content to have an incredible taste after 3 hours? (I no longer eat beef so I would love some insight/feedback from the beef afficionados.) Many thanks as always!
