umm you want "candied" or "preserved" lemons? They are different and I just want to check with you.
I know it sounds odd but when I think of Moroccan cuisine, I think more along the lines of preserved lemons.
I don't know Lasalle very well but a well stocked Middle Eastern shop should have both preserved lemons and saffron.
I know it's not in your area, but Akhavan will have both (the saffron is behind the counter near the pastries; just ask the counter guy)
