Not a lot of info to go off there cousin. I am a leg man myself but I would bone it & lay it flat rub it with the flavours you like then smoke it. I like garlic,lemon,parsley ,EVO,CBP,rosemary or go middle eastern .I have put chermoula on here before its Morrocan/Turkish I am not that computer literate but if you search via that word chermoula my recipe will come up..Its a wet rub of spices,fresh herbs,EVO.
Or you can look back through my posts on lamb & goat to see if there is something in there that you can go to school on.
I will be doing a shoulder tomorrow but cant promise that it will be in smoker.
PM if you need any thing .MICK
