I know, I know, I'm totally out of control. Can't help but owning them all, gives such variety to cooking. I'm a spice snob. Check out Penzey's for the best.
Their last catalog was quite impressive; featured more vegetarian recipes than ever. Recently they've dropped the selling of their sea salts, creating more and more spice blends to flavor without the addition of salt, following the healthier trend.
Some of my tried and true absolute favorite staples are: Maharajah Curry Powder, Fajita Seasoning, Paprika Smoked Spanish Style, Smoky Seasoned Salt, Tellicherry Coarse Grind Black Pepper, Mignonette Pepper, Shallot-Pepper and Country French Vinaigrette (dressing base).
