Can anyone suggest non-dairy substitutes for butter and buttermilk? Does anything come close to the taste of the "real thing'? I guesss I can substitute margerine for the butter, but is there anything better? Thanks
You can substitute olive oil--even when baking--though I would adjust the recipe a bit adding a bit less oil than butter and a little extra liquid.
Margarine? Ooh...ick. That stuff's nasty.
What kind of applications? In baking, various vegetable oils can be used instead of butter. In a sauce, I've used raw cashew butter to create body and opacity instead of cream. I don't know exactly what I would use in place of buttermilk...I've never really found a soy yogurt that's really good, but for baking it might work to thin it a bit and perhaps add some vinegar or lemon juice for acidity.
I could probably suggest more subs if I knew specifically what you were making.
