Monosodium glutamate. And then what is prickly ash powder as opposed to Szechuan peppercorn?
There is nothing wrong with monosodium glutamate and prickly ash is a well-recognised alternative name for Sichuan peppercorn and a lot more transparant than E621 or HS code 29224220 as used in many non-Chinese products, but those never seem to bother so-called MSG intolerants.
But this has been discussed to death on other topics here.
