I thought that any margarine would work. I quickly found out that many margarines contain whey or casein. Thank goodness label reading has become second nature.
NUCOA Real Margarine, stick version, distributed by GFA Brands, Inc.
NATURAL OIL BLEND (PALM FRUIT AND SOYBEAN OILS), WATER, CONTAINS LESS THAN 2% SALT, NATURAL FLAVOR, MONOGLYCERIDES OF VEGETABLE FATTY ACIDS, SOYBEAN LECITHIN, VITAMIN A PALMITATE, BETACAROTENE COLOR, LACTIC ACID, POTASSIUM SORBATE AND CALCIUM DISODIUM EDTA TO PROTECT FRESHNESS.
There is a tub version of this product which no longer states that it is milk free.
According to Nucoa's manufacturer, all Nucoa margarine is free of any and all milk. The lactic acid in Nucoa is derived from corn and all flavors are non-animal as well, thus the reason this product is so highly promoted by vegans nationwide. The labeling changed due to it's reduction in total fat from 10g to 7g.
Unfortunately, Nucoa is available regionally, being most commonly available in California, Arizona, Nevada, Utah and Idaho.
I would love to hear about other great butter alternatives available.
