I also ended up buying some pork rib tips, tofu and a mystery leafy green vegetable.
Once home, I cooked up a batch of mapo tofu. Mapo tofu is a traditional Sichuan dish with tofu and pork and lots of hot chili-bean sauce. Literally translated, it means "pockmarked grandmother's tofu." I always thought it was so named because the beans/chilis/pork resembled a grandmother's pockmarked face, but the references online appear to universally state that it was named after an old woman during the Qing dynasty who served this dish in her restaurant. I guess it's more appetizing to have a dish served by a pockmarked old woman than to be eating her face.
