The sundae combines the fast-food chain’s classic vanilla soft serve with coriander crumbs and is drizzled with bright green lemon and coriander sauce.
Those keen to try the unusual dessert have just a few days to do so, as it is only on sale from 21-25 February, United Daily News reports.
News of the launch has divided social media users, with some eager to try the sundae and others vowing that they “will never eat it”.
A picture of the sundae, shared by Twitter user Daniel Ahmad, has received more than 1,000 replies.
“Cilantro ice cream is really f***ing good,” one person said. “Anyone who hasn’t tried it should - spicy and sweet/creamy, does amazing things on your tastebuds.”
Another wrote: “I’m extremely interested.”
Others were less convinced. “This is a crime against humanity,” one person said.
“I’m literally shaking and crying and throwing up at how offensive this is,” another wrote.
A third said: “If hell exists, I would be force fed this all day long. Seriously though, even if you like cilantro would you want THIS? I puke a little every time I look at it.”
Coriander, known as cilantro in the US, has long been a divisive flavour.
People who dislike coriander commonly report that it tastes like soap. The study found that those who had the olfactory receptor gene OR6A2 will likely detect a soap-like smell from coriander.
Many Twitter users have expressed their distaste for the herb following Ahmad’s post.
“Might as well just eat a bar of soap,” one person said.
Another wrote: “Now I can have a sundae that tastes like soap.”
“Who cares about pineapple pizza when soap sundae exists,” a third said.
