On the TasteAtlas website, its description of kaya toast calls it “a popular Malaysian and Singaporean breakfast”. However, it attributes the dish only to Singapore.

Kaya toast is believed to have originated with Hainanese people who worked on British ships as cooks and later settled in Singapore, where residents “replaced the British jams with local coconut spreads”, the site states.

“Now even kaya toast [42] has been stolen [from us].”

Comedy site Mgag shared the same sentiment on Monday, using a popular reaction image of cartoon character Fry from Futurama narrowing his eyes to represent Malaysians’ reaction to kaya toast being identified as Singaporean.

As of Wednesday afternoon, Mgag’s Facebook post has received 5,100 reactions, 630 comments and 520 shares.

Another meme posted by Mgag in the comments section, which depicts Singapore as a masked thief pickpocketing “kaya toast” from an unsuspecting Malaysia, has 1,200 likes.

Likewise, under Mgag’s Facebook post, one Malaysian online user said: “I eat before, Singapore kaya toast, the roti [bread] size is [shrunken] 3.5 times.

“Even Hup Seng biscuits [are] thicker than their kaya toast.”

Some also poked fun at Singapore’s limited land area and reliance on imports, writing: “Ah, yes. The kaya toast made locally in Singapore from their vast pandan fields, fresh farm eggs and vast coconut plantations.”

Others joked that the Malaysian government would soon be discussing kaya toast in parliament.

Just last month, the government there gazetted bak kut teh – a pork bone soup made with aromatic herbs and spices – as one of 10 national foods to preserve Malaysian heritage. The move was reportedly proposed by a lawmaker in June last year to prevent Singapore from “claiming” the dish.

As for kaya toast, there were more people who felt that there was simply no need to kick up a fuss about the rankings, referring to another recent report that named Malaysia as the fifth-happiest country in the world. Singapore, on the other hand, came in 21st.

A top comment on the post read: “We are happy people. Please relax. We are [the] fifth-happiest people … They wanna claim, ah? Shake hand and take, lah. We love you, lah.”

Is Malaysia set to become a start-up hub that can compete with Singapore?

The report, published by non-profit neuroscience research organisation Sapien Labs on March 4, is based on a comprehensive assessment of mental well-being. It has been widely reported in Malaysia.

Malaysian online users also pointed out that regardless of origin, kaya toast is much more popular in Singapore since shops such as Ya Kun Kaya Toast often entertain “full houses every breakfast, lunch, tea time and maybe dinner”.

As one Facebook user wrote: “Seriously, who cares which country it belongs to, as long as it tastes good?”
