“The outer fruit layer, left on black pepper, also contains important odour-contributing terpenes including pinene, sabinene, limonene, caryophyllene, and linalool, which give citrusy, woody, and floral notes. These scents are mostly missing in white pepper, which is stripped of the fruit layer.”—Wikipedia, peppercorns.
So I would guess something in all that doesn’t smell great when soaked in water. Also if you read about black pepper, white pepper is basically soaked black pepper—the fruit comes off and the dry seed it used, so that is another possibility.
@EmpressPixie oh right… well these were tropical mixed peppercorns.. so a mixture of white, green and black…very bizarre…
Now that there’s a serious answer, can I resubmit?
Peppercorn’s fart? Who knew?
Take it off again if you need to, but I think it’s funny.
They fermented. This often happens in the soaking stage of turning black peppercorns into white. As for what chemicals cause the odor, a study that researched off odors caused by fermentation in white pepper powder isolated these compounds by spectroscopic analysis:
3-methylindole (which causes fecal, swine-manure-like odors), 4-methylphenol (which causes fecal, horse-like odors), and butanoic acid (which causes cheese-like odors).
excellent Harp!! thank you! now I know why I really didn’t want to eat the peppercorn sauce!! or anything associated with it for that matter…. :@)
