bbq: I made some bbq sauce (home made) and I am wondering how long will this last in the fridge? It has a lot of vinegar and some sugar. I assume this will make it last? How long?|||7 days|||should last a few months at least but a proffessional would tell you not to use it after a few weeks at best. Mold can grow around the lip of the container even if lots of vinegar. If you are going to properly bottle it then it could last much longer and won't require refrigeration. Google canning (jars) its actually easy but be sure to follow directions.|||I second freezing. Do it in little plastic containers. If it's got a lot of vinegar and sugar, then it will last longer, maybe a month.|||If it is sealed it should last about 3 months maybe 4. You can also freeze it in jelly jars for a later use.
