I recently figured out the recipe for garlic vegan butter which is made primarily by roasting garlic, then whipping it in a blender with coconut and olive oil, and cooling in the refrigerator. It's delicious, textured similarly to butter and, as far as I know, not terribly unhealthy.
Then my father mentioned to me that that is similar to the process of making hydrogenated oils. I DO remember once reading something about whipping oil being a bad idea. Is that true? Am I basically just quaffing hydrogenated fats?
