About Colorado Lamb
Colorado has a strong ranching heritage and lamb plays a big part in our history. Colorado Lamb is highly sought after due to its quality, and consistency in flavor and tenderness. The majority of lamb are free range, grazing on grass, brush and sage in the foothills of the Rocky Mountains. And even graze in Colorado Vineyards. Colorado lamb is hormone and antibiotic free.
Lamb raised and imported from New Zealand and Australia are smaller in size that American raised lamb, and bring with it a gamier flavor. Please support local. Ask your butcher for Colorado raised lamb.
Preparing a Frenched Rack of Lamb
At Cooking School, we prepped a Frenched rack of lamb. New for me. After being handed a rack of lamb we were instructed to clean the bones using the “frenching” method. It truly was a labor of love, and a very difficult task.
I wrestled with that chunk of meat for over an hour, and I swear there was a moment where I thought I’d cry out of frustration.
Frenching a rack of lamb means to strip meat and membrane away from the bone to give it a clean appearance. See that beautiful little clean handle – that takes a lot of work.
Our knife skill training at school was extensive and I’m very glad for that. However my boning knife and I still aren’t speaking over the whole ordeal. Here’s a link from Serious Eats if you’re interested in learning Knife Skills, How to Clean and French a Lamb Rack.
