I believe that Mother's margarine is dairy-free - don't know about the
citric acid. If it says Pareve, which is what the last package I bought
said, it is free of dairy products.
And this is the time to buy it since it floods the supermarkets prior to
Passover. A package that I returned a couple of months ago was dated as
expiring last summer (!) - I'm pretty sure it was left over from last
Passover :-(
