Chinese New Year 2015

Raw Fish Salad during Chinese New Year

One of the most significant Chinese New Year food that Singapore has created. The 发财鱼生 which is raw fish in a salad. Created by 4 chefs in Singapore back in the 1960s, it is a delicious dish with many good chinese idioms accompanying the ingredients. The action of tossing the salad is also unique in food culture.

Ingredients include: white radish, carrot, pomelo, ginger crackers, sesame seed, plum sauce, cooked oil, grinded peanuts, cinnamon powder and most importantly raw fish.

A great accomplishment by Singaporeans.
