the vinegar looks clear, but i don't know what that means. i'm going to try it tonight, and if i wake up feeling like garbage then i'll throw it away.
there was a quarter cup of vinegar left. i initially put a quarter cup of water, two tablespoons of cayenne pepper and some unmeasured amount of sprinkled onion salt that i'd guess was a teaspoonish. it wasn't dissolving in the measuring cup, so i put it in a bottle and shook it. the mixture is a darker colour than frank's, but doesn't taste that different. i added a bit of water (unmeasured), another chunk of cayenne that had bunched in the container and a bit of onion sat that had bunched and started shaking it. i may add more of each item.
i suspect this will need to sit a day or two but i'm going to try it in the guac tonight anyways.
