Excellent QDM! I had to look high and low to find the lamb you suggested and finally found it at Whole Foods Market. I'm glad I waited. The lamb was delicious and pink and melt in your mouth tender. Delicious marinade. The grilled pearl onions were outstanding and I wonder why I never thought of using them on kebabs. I served this over a plate of couscous and it was yumyum. :-) Very nice curry dish, dear.
