Mother's  margarine is available year round and is dairy free. There may
be one that does have dairy as well.  The margarine that becomes
available this time of year is kosher for passover, meaning it contains
none of the forbidden grains.  Most margarines contain soy oil but for
passover that is forbidden.  I think that the passover marg has
cottonseed oil.   Pareve marg is available year round in any kosher
market or store wih a kosher section. The passover marg is acceptable
for those with soy allergies but is terribly unhealthy.
