They may not sound appetizing, but boiled pig's trotters are a beloved local delicacy in Chengdu, affectionately known in Chinese as "old mother's trotter flowers". The "flower" part of the name comes from the fact that the trotters are stewed long enough for them to fall apart like flower petals that spread across the rich, milky broth. Take a bite of the tender meat, dip it in aromatic chili oil, and you'll have a symphony of flavors and textures that will melt in your mouth.
