Man, I love grilled lamb and the best grilled lamb I've ever had was in Morocco. I grill it myself nowadays, but like everything else I make more than once, I have my own variation.
I live in the Holy Land, and I invited a local Arab-Palestinian guy (Khalil) over. He asked what I was cooking. I told him "bbq kharouf" (grilled lamb). He asked how I was cooking it, so I told him I would cut the lamb into 1" chunks, then marinate them in olive oil, rosemary, and salt. Then I'd grill the chunks on skewers over citrus wood charcoal. He said, "No that's wrong." (Most Palestinians have exactly one way of doing things and aren't big on change
.) I said, "Listen up, Junior. If you don't want to eat it, I'll eat your portion. Just stand back and I'll take care of this."
When he tried it, he smiled and said "Very nice." More importantly, he asked for seconds. The next time we got together he asked me to make it again. When he showed up, he had 4 skewers of nothing but salted lamb fat. No meat at all. He cooked them on the grill until they were nice and browned, then offered me one. I only tried it to be polite, but WOW. Now, I love me some lamb fat kebabs, and I don't throw away any lamb fat.
