I bought an herb called zataar at Richter's Herbs this summer; it's like oregano. I only know what I've read about it. Apparently the name also applies to a blend of the herb with sesame seeds as well as sumac.
Is there somewhere in Toronto where I can buy sumac?
Are the berries which grow on sumac trees around here the same stuff? When should they be harvested? How are they processed? (My Moroccan neighbor says the sumac he has seen used was in a powder form).
