Unless you travel the world like Bill Penzey and search for the
best and original, not sure what you are asking for? Several chef friends of mine use
Spices, Herbs, Seasonings and Culinary Ingredients | Spices Etc. and use that in addition to Penzey. They offer some very differnt mushroom and herb treats.
When I was in Turkey I discovered Aleppo peppers, wowzee, got home and it was in my next Penzey catalog
But best of all you must check out the Spice market in the Grand Bazaar in Istanbul.
There I got saffron from Iran, the best for $9 an ounce, the best in America at that time was going for $9 a gram. When they were putting my coriander, tumeric, paprika in little ziplocks the aroma was amazing and the prices made me swoon.
What is the competition where you are, is it a major city. Would Penzey give you a franchise there??
Maybe do tea or coffee to get people in?? offer olive oil or vinegars. A shop in Seattle has olive oil tastings that call me in.
Also as stated above check out Indian, Asian, Mexican shops and if you have room grow some fresh hers or find them from gardeners in the area?
Also is there a farmers market when you can offer you goods during the summer and get you name around for year round?
Good luck,
