Earth Balance is one of the most awesome things to happen to margarine in like... ever. I love that it's not hydrogenated. I love that it tastes awesome. I love that it comes in sticks and tubs. And now, I love that there's a soy-free version! I wish this also came in stick form, I have to say, but I don't really mind just scooping it out of the container to use in recipes. It seems to work just as well.
I haven't done a side-by-side taste comparison, but it tastes pretty much the same to me. I'm not supposed to be eating soy as often as I might like, so this is a product I was really excited for. It came to the US before Canada and I was chomping at the bit waiting for the day when I could finally buy it. I think I pestered the customer service people at Whole Foods at least once a month asking when it would be available.
If you're trying to avoid soy for whatever reason, this stuff is for you. I think it's good to get more of a variety in the foods we eat, anyway. My naturopath tells me that sometimes eating too much of a particular food can actually cause a sensitivity. It's interesting how much soy there is in pretty much everything when you start reading labels. Soy lecithin in particular is hard to avoid. When I was doing an elimination diet about a year ago to try and get some of my food allergies sorted, the lack of soy-free margarine was a real kicker. I was using coconut oil as a substitute for margarine on toast, but it's hard to replicate this flavor on things like baked potatoes and the like.
Soy-free Earth Balance, I <3 you.
