Re: Since your mash doesn't have salt or preservatives, what kind of shelf life does it have? The shelf life, as long as it is unopened, is nearly unlimited. The only thing that happens over time is a bit of oxidative browning where the chiles contact the sidewalls and the head space. This is only because there isn't an oxygen proof (cost effective!) plastic on the market yet. Re: Why are you able to get away without any? Because of the heat treating. My method is essentially 'canning' just like our parents (or grandparents if you're young ;-) used to do, except I can into 5 gl buckets. The heat treating, if done correctly, combined with the very low pH, sterilizes the mix. Re: What's in the other 25? Water, vinegar? I believe by this you mean the 25%. Mostly it is water and vinegar as you guessed, though this can vary greatly from manufacturer to manufacturer. Re: Is it the stuff cheapskates are using to cut their mash percentages down, that need the preservatives? Not really. It is more of a processing choice. As heat treating is expensive and labor intensive, not many (if any) do it. Bit of chest thumping here- maybe that's why CaJohn (who uses the chiles done this way almost exclusively) has over 200 major awards :-) I've over a dozen myself just by accident since I don't usually enter contests. I'm more likely to get away with the expense of it because the mash production from my fields is measured in only a dozen tons or so, not hundreds of tons. -Jim C Mild to Wild(R) wildpepper.com
