Throw it out. Not worth the risk.

Was this hot sauce canned according to established canning practices? Was it refrigerated? Regardless, it sounds like you have spoiled goods and unless you want a day or two of misery, you had better write it off as a loss.

I would think not enough acid, and as esox07 asked did you follow proper methods? I use 5% acid vinegar as well as lime juice. This batch you are dealing with throw out for sure.

Toss it. Sterilize whatever it's in and sterilize it again, or toss the container(s) as well.

Get rid of it. The green mold is just the fruiting body of the fungus it most likely runs through the whole jar so will always return.

Yep, check for roots under that green canopy.

Thanks folks. The consensus is unamimous. Out it goes. I have faithfully checked the pH of that jar as well as all of my others. It ranges between 3.8 and 3.9. I even have another jar of the same mix that does not have the mold, nor do any of the other batches. Guess I got something foreign in this jar.
