What to do with disgustimg avb butter

I made butter. It smells and tastes disgusting. I even did some water curing for 24h. I don't know what to do with it. I can't eat it, I just tasted a small piece and the smell and taste was so awful. I don't think it's gone bad or something, it's just the avb smell and taste that seems concentrated in this butter.

Any ideas what to do with it? How can I process it to mask most of its taste. Should I throw it away? Urgh I can smell the picture.
