After traveling in Malaysia with my son, we stopped by Singapore on the way, and you must try the bak kut teh in Singapore.
Bak kut teh originated in the 19th century, linked to the historical period when Chinese people migrated to Southeast Asia ("Nanyang"). At that time, the immigrants worked as coolies in places like Singapore and Malaysia. Needing high-calorie food to replenish their energy, they boiled cheap pork bones with other ingredients to make soup. You must try this most famous soup.
