Another spice source

Epices de Cru in Montreal is another great option: LINK
Many very interesting blends, with an emphasis on whole spices that you must grind.

If you like blends, La Boite In NYC is full of very creative combos: LINK. I really like the Sel d’Antibes, a kind of citrusy salt.

And if you’re looking for obscure stuff, it is hard to beat Kaluystan’s: LINK. Really global in its stock so you can get Persian dried limes, white poppy seeds, or barberries…..very diverse selection.
