Suan La Fen (Hot & Sour Glass Noodles)

Suan La Fen's slippery sweet potato glass noodles swim in a sour, fiery broth crowned with peanuts and preserved vegetables—Chongqing's definitive street noodle. A single bowl contains 400 calories and delivers a spicy kick measuring 8,000 Scoville units from its chili oil, making it 25% hotter than the average noodle dish. This soup is 50% cheaper than #6 Egg Waffle per serving at $2, while offering a richer umami profile thanks to 5 grams of fermented vegetables. Chefs recommend 10 minutes of prep time for the perfect texture.
