I think all major commercial margarines use solvents in expelling oils. I suggest either Earth Balance margarine, or Spectrum's new unhydrogenated organic margarine. Both are very butter-like, neither is hydrogenated nor GMO. Willow Run is another. The "margarine page" lists a number including Fleischman's as being all vegetable. http://www.skyisland.com/OnlineResources/cookbook/milkfree/margarine.html I hope this is helpful and not confusing.
