Why is bánh chưng eaten with pickled onions? A fun explanation
Did you know? It is the subtle, harmonious pairing of a light, tangy sourness with rich fattiness that makes bánh chưng even more appealing.
Every Lunar New Year (Tết), almost every Vietnamese person recalls the famous couplet "Fatty pork, pickled onions, red parallel scrolls / Nêu pole, firecracker strings, green bánh chưng".
Today, "the nêu pole" and "red parallel scrolls" are no longer as common, and "firecrackers" were banned long ago, but "fatty pork, pickled onions and green bánh chưng" will surely endure and remain indispensable on the ancestral offering tray of every Vietnamese family.
