Like with various products, like yogurt, sour cream, ranch, etc. It gets these horrible crusties around the outside and I lose my appetite it looks so nasty and end up not eating it.

I'm too scared to clean the crusties because I think they might fall back in the product

ouch, im a crustie

When I open milk cartons, this happens. It doesn't really bother me though.

I just take a rag and wipe it off. If it starts to fall into the bottle, then the bottle is trash.

There's really nothing bad about it. Just try to forget its there. And never eat out again.

well in that case, no, why would i throw it away.

i generally wipe the lip of the jar when its still wet anyway

Just don't touch the 'crusties' with your spoon? That's what I do. Usually the 'crusties' are just dried up 'product' and if you mix it back in it'll be fine.

And dammit I hate your use of terminology.
