With my peanut butter, that is. No worries..... I have been wanting to find a good alternative to the Peter Pan and Jiff stuff, that is laced with Rape Seed/Canola Oil - google up that stuff and it'll scare the Hades out of you! So, I have been using Smucker's Natural Peanut Butter - very good stuff! It's in a glass jar, and must be refridgerated after opening - no preservatives. Interesting texture - even the Smooth has wee bits of peanut - I like it! It has to be stirred before use, as the oils do separate. They make a good natural Syrup too. I can feel better about using them now. Prices are nearly the same as the Big Name preservative-laden products - so cost isn't an issue. I did an experiment awhile back. Took a dollop of Peter Pan P-butter and put it in a bowl, and it's been sitting for over a year now..... No mold, no bugs, no .... anything..... It just sits there, never changing state! It's like peanut-flavored plumber's putty..... I WILL NOT put that stuff in my belly again.
