Well, I'm going to go out on a limb here and guess that the reference to McCormick's "Seasonal" may have come from one of the recipes that IcyMist posted (Sweet Tomatoes Cream of Broccoli Soup
) in response to your request for recipes from Sweet Tomatoes/Souplantation
that you started: Sweet Tomato Soup Recipes? (Souplantation)
in the Soup Forum (which appears to have maybe originally come from Uncle Phaedrus, Finder of Lost Things
website under Souplantation & Sweet Tomatoes' Recipes
or wherever Uncle Phaedrus may have found it)?
I'm going to guess that this is a typo and should read McCormick's "Season All" since - McCormic doesn't appear to make a "Seasonal" herb/spice blend and, if they did, wouldn't you need to know which "season" it was seasonal to?
