Oh dear, oh dear, oh dear! I read an article on the 'net about canning butter; it was really only putting melted butter in jars and sealing it. I did over 30 lbs. of it...now I find it may contain botulism!? I guess I'll start emptying the jars and washing them, a little at a time, so DH won't wonder why I'm throwing out all that butter. At over $4.00/lb, that is a lot of $$ to get rid of. *sigh
