Do all human racial/ethnic groups perceive food tastes & flavors the same way?

Nope but you made me smile. Marmite is a British invention and very popular in Britain. Curiously there is a specific New Zealand version which covers Australia and the Pacific - it’s said to be slightly milder.

Australia is the home of Vegemite but it also sells well in the UK.

Marmite was *invented *in England, the main factory is in London. Vegemite is a rip-off concocted decades later.
