I just returned from a trip to Morocco with an extra bag packed with spices--ras el hanout, dried ginger root, long peppercorns--the options were seemingly limitless. While I lugged my spices around Morocco, a friend on the trip said she would just keep ordering all hers from Penzey's. Fair enough—Penzey's does produce first-rate spices.
My supply of spices comes from a few different locales. In New York, my go-to source for spice is Kalustyan's. Whenever I'm in Atlanta, I make sure to hit up the DeKalb Farmer's Market. And when I'm in Alabama, I steal some chile powder from my mother. She picks chiles fresh from the garden, dries them for months, then grinds them into powder.
Those are my main spice sources, but it's just the tip of the iceberg. What are your go-to places for the best spices?
