DH and I made this delicious shepherd's pie a few nights ago and really enjoyed it. We used two pounds of lamb chopped of from a big leg of lamb, rather than using blade chops. I also used salted butter with no problems. Even though I used a 9 inch pie dish as directed, my pie spilled over the sides into the oven while cooking, so be careful. The only problem was the bit of mess in the oven, the pie looked and tasted fine. The recipe is from Williams-Sonoma.
