Shoarma is so popular in Holland that you might forget it is from the Middle East! When we lived abroad I really missed it and tried to copy the spice mix that you can buy here in the shops. There are many makes and blends in the shops, they all taste different, now try the homemade mix! Note that there is no salt in the mix so do not forget to add with cooking, or if you give this as a gift to mention it. After you have tried this you can always make some changes to suit your own taste.
