I don't know why an emetophobe would "take a chance" when can't you
just go get an unopened jar? A non- ephobe would take a chance but
someone who would rather go for a swim in hot lava than v*, would use
the honey instead. Look for mold in it and make your decision. Like I
said, i'd bet money on it that you'll be fine but if it's going to make
you worry for the next 3 days then its worth the 80 cents to go buy a
new jar or try to choke down a PB & honey sandwich.
