Great - remind me before we see you next time and I'll package some up so you can try it, Would be interested in how it compares to what you've tried. Do you have za'atar? If not I can give you a bit to try out as well.
In the mean time I expect you to be working on a terrine that includes ras el hanout
BTW, pan roasted some cherry tomatoes in sumac last night to serve with pork medallions with berbere. Simple and very tasty in a lemony sort of way.
