I must have alot of time on my hands if I'm finally getting around to thinking about this! I mostly try to use the more common seasonings from my herb garden, but I have 20+ spices in my pantry that I've had anywhere from 5-10 years; curry, tumeric, paprika, allspice, creme of tartar, etc. I know McCormick's encourages you to replace every 2-3 years depending on whether it's ground, whole, etc., but I'm loathe to believe this at I assume it's smart marketing.
When I smell these spices they seem to have retained their aroma and I'm nervous to toss against the day when I'll have to run out mid-recipe to replace something.
If you suggest I replace, does anyone have an opinion as where best to buy. I've bought good sized bags of spices before at ethnic markets for a fraction of what I'd pay for McCormick. Thanks so much.
