So my plan for St. Patrick’s Day was to make Shepherd’s Pie and post about it. Unfortunately, I had such a splitting headache when I got home from work that I couldn’t concentrate. I’d bought ingredients very specific to this recipe from the February 2009 Martha Stewart Living, but at the time I couldn’t remember where the recipe came from for anything. I tore through every cookbook, magazine (I thought), and website I use looking for this recipe. But the ones I found all called for ground lamb or different cuts of lamb. And since I’ve never cooked a lamb shank before in my life, I had no idea how to adapt what I had for those recipes.
