I volunteered to put the tomato-flavored "BBT" — the Singaporean term for boba — to the test.
There were around 20 people at the Gongcha outlet I visited at Somerset 313, a mall along Singapore's Orchard Road shopping belt. A few of them pointed and snickered at the sign advertising the tomato teas, but none of them ordered the drinks, going for conventional milk teas with boba pearls.
With great trepidation, I watched as a staff member at Gongcha Singapore mixed up my drink. He squeezed an honest-to-god bottle of Heinz's tomato ketchup into what looked like a shot glass, before emptying it into a cocktail shaker.
Heinz's and Gongcha's representatives told me these drinks were exclusive to Singapore.
