If you wanted to make a variation on this, because you could not add harissa due to food allergies, would this Ras el Hanout work? The ingredients are: cinnamon, ground ginger, garlic powder, cumin, coriander, cardamom seeds, nutmeg, black pepper, cloves, salt and turmeric. (I'm making my own, leaving out the spicy peppers, also due to health concerns.) And if so, how would you change, if at all, the spice mixture called for in the recipe? Thank you so much. ;o).
