    I sliced the lamb and served it in tortilla wraps with the sauce. I will be making this sauce for a long time to come is excellent! It would work with any barbecued meat.  -  30 May 2009


    Altered ingredient amounts. I added fresh tomatoes to thin the sauce out & then I pureed it.  -  30 May 2009


    We sliced it and served it in wraps with the sauce - delicious. I will make the sauce again for sure & use it with chicken or any other barbecued meat.  -  13 Jul 2009  (Review from Allrecipes US | Canada)
