Where do the chef's shop?
Are there any special professional shops in the GTA where I could buy ingredients used in baking and gourmet cooking?
Madeira - LCBO
Creme de Noyaux (note spelling) is a liqueur that the LCBO apparently doesn't carry. It's almond-flavoured, so perhaps you can substitute Amaretto.
Orange flower water - try the Cheese Boutique or Pusateri's.
Brown paper for baking? Probably widely available. Ask your local baker...
re: mtl to tor
Try Arz (Iranian) at Vic park and Lawrence or Iqbal Kebab and Sweets in Thorncliffe for the orange blossom water.
Also, the dry goods store (the one in the centre behind the veg stand that has kefir lime leaves and thai basil) the basement of the South Market (St. Lawrence) has it at a fair price.
