This version features a spicy beef broth simmered with lemongrass, chili oil, and annatto for its signature reddish hue, served over round rice noodles with thin slices of beef, pork knuckle, and blood cake. The kitchen offers a beginner-friendly option with just beef slices to ease into the bold flavors. Fresh herbs, lime, and pickled vegetables arrive on the side for customizing each bite. Diners note the broth's depth builds from the initial heat to lingering savory notes.
