Hot and Sour Glass Noodles 酸辣粉 (suān là fěn) dates all the way back to the Three Kingdom Period. People also call it “Brothers” Hot and Sour Glass Noodles 兄弟酸辣粉 (xiōng dì suān là fěn). Three best friends invented these noodles, one became a king, one a general and one a God! Here’s the story behind this iconic bowl of noodles….
During the Three Kingdom Period, three best friends came together and shared a common goal to fight for their kingdom, Shu or Shu Han 蜀漢. They were: Liu Bei 劉備, Guan Yu 關羽and Zhang Fei 張飛. Their fame was further heightened when their stories were written into one of the most famous novels in China called Romance of the Three Kingdoms 三國演義.
They were all warriors when their friendship began. As they fought in battles together, they became more than just friends, they became brothers. One day, they had dinner at Zhang Fei’s house and they decided to make a dish that would symbolize their brotherly bond. The long and thick sweet potato noodles represented the strength and longevity of their friendship. They added honey, pickled mustard greens, coptis (berberine is the medicinal ingredient in coptis and is very bitter), and chilis. These ingredients represented the four tastes: sweet, sour, bitter and spicy. In Chinese, we often describe life’s challenges with these four tastes, 甜酸苦辣 (tián suān kǔ là). And so it represented that they would go through all of life’s challenges together.
One of their famous quotes used in many Chinese movies and TV shows is “不求同年同月同日生, 只願同年同月同日死.” This means “we can’t ask to be born on the same day, but we ask to die on the same day.” That's pretty heavy stuff! Liu Bei became the King of Shu. Zhang Fei and Guan Yu were Liu’s generals. After Guan Yu died, he was praised for his loyalty and bravery and then they started to worship him. He is believed to be the God of War and is still widely worshipped today.
So, guys out there, know what you’re getting into when someone offers to share their Hot and Sour Glass Noodles 酸辣粉 with you! Do I hear “bromance?!”
My Hot and Sour Glass Noodles 酸辣粉 recipe doesn’t quite have a bitter taste, but that’s how most people like it. Some people make it spicier or more sour, and it’s up to you to make it your own. This is a Sichuan dish that is extremely popular in China. If you ever go to Chongqing where they’re famous for this dish, it’s a must try! But make it yourself first! I made it into a vegetarian dish because it’s easy enough to make it non-vegetarian. You can add any meat even ham or fish balls. Seafood would go great with this taste too.
