Thanks for sharing, Octarine!
Unfortunately I didn't get your message before I went home last night, so I experimented on my own, modifying from a recipe I found for making the grilled version of this lamb.
I first toasted some cumin, red pepper flakes, and szechuan peppercorns then ground them up. I eyeballed the amounts and adjusted to taste, but it was about equal parts cumin and szechuan peppercorns and a little less of the red pepper.
I marinated thinly sliced pieces of lamb from a boneless leg in some vegetable oil, about 1 tsp of soy sauce, the spice mix, touch of garlic powder, and salt and black pepper for about 20 mins. I added about 1/4 tsp of cinnamon, too, but I don't think I could distinguish it in the final dish.
I went light on the soy because I read an article where a chef from a restaurant who makes the grilled version said he never uses soy sauce. But I thought it couldn't hurt.
Next, pan seared the lamb pieces and set them aside. Then stir fried onions and red bell peppers, adding whole cumin seeds then the lamb.
My critique:
The lamb had pretty good flavor and was close to LSC's. Next time I'd add even more spices and up the heat in the marinade. May try adding sherry and a little more soy as well. It'd probably also benefit from a slightly longer marinating time.
I couldn't remember how saucy LSC's version was, if at all. Mine was on the dry side, though it had a little sauce to it. Next time I may try adding your seasoning sauce.
My veggies didn't have much flavor. Probably b/c I didn't add any sauce to the dish, so I should have salted more as I was cooking them. Small dried chilies would be a good addition.
Overall, I was pretty satisfied with my first time experimental effort, though I would've preferred even stronger flavoring. I'll keep working on it and take your suggestions next time, too.
