I found it difficult to find Nucoa in the East about 1980 when I was on a research trip, but have used it for years because it's one of the few margarines that contains no milk. Now we're into Brummel and Brown yogurt/margarine stuff for baked potatoes, at least, but we go through tubs in short order. For baking I do use butter-flavored Crisco. Margaret If you like the Brummel and Brown stuff, you'll flip for Corman's Light Butter. It's imported by Scratter Foods from Belgium and doesn't have the slightly oily feel/taste that the Brummel and Brown does. It really does taste very much like fresh, unsalted real butter. And I am a butter purist...I can't abide margarine and will either do without or use real butter. One thing I'm unclear about is the lactose intolerence issue. Since butter is 100% fat, I would assume (always dangerous) that it has no lactose, since lactose is a sugar (carb). Yogurt, on the other hand, would seem to aggravate a lactose intolerance, since it is a milk product. But I am horribly ignorant when it comes to chemistry....Liz, you'd know, so speak up please!!
