A bit of patience is required for the stages of browning. It's worth every minute. Some say, just hold the beef for a day and make endless quantities of hash. This recipes redefines hash. Serve with a big green salad and maybe some fruit for dessert. Or the leftover dessert. We had a cranberry cake with an orange glaze and a cranberry-orange compote that was as good, in its way, as the hash. The holiday lingers.
Here is another photo of the roast. Just to inspire. Those at the table who aren't crazy about medium rare can eat the end cuts. We had just enough fat for Yorkshire pudding. These roasts aren't as fatty as they used to be. It was well trimmed but not fat-free, never fat free.
Whenever any group has a "concerned" in its name, run like hell the other way. Fast.
