American living in the UK here, try buying the huy fong brand on Amazon and see if you like it. I think it's far superior.
I'm not saying you can't buy it on Amazon and I don't know enough about nutrition to know why E222 was banned.

Edit: I am wrong on the internet. I just checked my bottle in the fridge and it is GoTan [1] Sriracha, from the Netherlands. With a green cap, too. I feel kinda ripped off, tbh.
The green cap meant that beautiful Huy Fong Sriracha, which has no mayo, but it's so distinctive that other manufacturers copied it, presumably to fool gullible people like myself
