There's nothing accidental about this--only I didn't notice it till afterwards. At the supermarket last week we found this Wild Mushroom & Port dip, reduced to clear. For $1, we were totally game to give it a try. After searching for the ingredients, which are around the outside of the label, I determined it was vegan so it got thrown into the cart.
When we got home and started digging in, I looked more closely at the lid... It actually says "Vegan" right on it! On the same label where I scoured the ingredients looking for animal products! The next time we went in the shops, we looked at this brand again, and all their dips have the vegan label. How cool!
I'm a bit obtuse sometimes, but when I make these discoveries I get very nerdily excited.
