I've heard that eating mango seed is safe from many sources, so I decided to try it tonight. The thing is, it was so bitter that I had to spit it out, thinking that the sources that I used could have been wrong. I mean this had to be one of the most bitter things that I have ever tasted. I then looked into half of the seed, and it was grey insede. Could this have been a fungus that did this? Sorry if this is the wrong forum group to ask, but I couldn't think of a better one to ask. Maybe there should be a culinary page, just saying.
