Ghoulish, give me a pitta bread, grilled meat and sauce/salad and I'm happy, regardless of recipe, but this shawarma hits the spot. A habit I have (good or bad) is to fiddle around with recipes... I like a bit more tang in kebab sauces. Do you have a chilli sauce recipe that would go well alongside the tahini?
Jerry...good to see feedback on the lamb version. I agree on the cinnamon & lime powder amounts... Don't be shy with them. (I assume you are using cinammon(cassia) powder and not whole bark).
Tha tahini paste, as you said, tastes surprisingly like hummus. I didnt have fresh parsley, so used a little dried, but added fresh coriander, and made sure there was enough lemon juice for some tang, as well as a squirt of tomato ketchup (hey... Nobody is perfect).
