One of the questions I received by email asked me to recommend a dairy- AND soy-free margarine. Until a few weeks ago, I would have been stumped. But now Earth Balance (our favorite margarine company) has a soy free variety.
Earth Balance Soy Free has a good buttery flavor, just like the other Earth Balance varieties. Tasting it side by side with their Soy Garden, it seems to be a bit saltier and a softer consistency.
I spread it on flatbread, and used it to make popovers and homemade brownies. It has a much lower smoke point than the Soy Garden or regular EB varieties. (Smoke point? Geez, next she'll be talking about the margarine's "mouthfeel.") The popovers bake at a high temperature and the recipe starts with melting the margarine in a muffin tin, so the Soy Garden variety smokes a bit, too, but not nearly as much as the Soy Free variety. The brownie recipe I made begins with melting margarine and baking chocolate over low heat on the stove. Even at a low temperature, the soy-free margarine smoked up the house. I couldn't taste the smoke in either recipe, though.
BUT! It is soy free! And dairy free! And tastes good! And would probably do just fine in muffins or a casserole! And it tastes very, very good spread on bread.
