We recently found some Follow Your Heart soy cheese mozzarella at our health food store and decided to try it for the first time last week. We used a little chunk on veggie lasagna then put the rest in a ziploc bag in the fridge. Today it has this weird reddish scum on it and smells really funny. My first inclination is of course to pitch it, but since we'd never used this brand before... is this normal? Did we store it wrong? It was good and a little pricey so if we don't have to throw it out we'd like to know. Thank you.
