Guilin Rice Noodles: Lactic Acid Grain Fermentation and Viscous Multi-Spice Brine

Dating back over two thousand years, Guilin Rice Noodles (Mafen) showcase wild lactic acid fermentation and deep botanical extraction. High-quality rice grains are soaked in spring water for several days, initiating a lactobacillus fermentation that breaks down complex starches and yields a subtle, clean acidity before being extruded into silky, elastic threads. This dry-tossed dish completely rejects watery soups, relying instead on a pitch-black master brine (Lu Shui). The intense elixir is slow-simmered for 24 hours with pork marrow bones, aged hens, horse meat, and over thirty medicinal herbs like dried lo han guo and sand ginger. Tossed together with crispy beef, braised horse meat, and sour long beans, the noodles lock in a deeply aromatic glaze.
