We've got a Penzey's spice shop near us and we go there once in a while, and make it a practice to try something new every time. Here are a couple of really good spice blends that are worth your attention:
Florida pepper blend: It's like lemon pepper but with more tartness. Really good with pork chops and chicken.
Turkish spice blend: Kind of like chili powder, but different. A lot of cumin in it. Really good in just about everything like stews, omelets, soup, sauteed vegetables.
Have you found any good spice blends?
