Bought this stuff thinking it was real mayonnaise. You would think with the name “Just Mayo” you would think it would be what it says it is.
BTW it tastes terrible.
In USENET's RFC, there was a big discussion on it last year, and how "Big Food", probably Kraft, was complaining about it.
Given that you just grabbed it because of the label, I'd say Big Food has a point in this case.
Tweaking the label isn't enough. They should just go with "Just Veganaise" or the like, and spend the marketing money and promote it as egg-free spread/sauce/dressing.
It does have its supporters, though.
