Well, ok, so the classic form of hash seems to require potatoes. My mom's hash definitely involved potatoes. But the thing I threw together Monday night seemed so hash-like, I couldn't say it was anything else. It's just that rice took the starch place of honor, rather than potatoes.
I improvised off of Ha Roda's recipe for "Egg and Pork Stew" in her cookbook A Vietnamese Kitchen. Marinate about a pound of ground pork in two tablespoons of fish sauce, one tablespoon of light soy sauce, one tablespoon of oyster sauce, some salt and black pepper to taste, one teaspoon of sugar, two tablespoons of chopped onion and two teaspoons of bacon grease. Stir-fry the pork for a minute or two, then add leftover cooked rice (about a cup) and stir-fry for another minute.Then add the egg and stir-fry. On the second day, I threw this over some rice noodles. On the first day, it was fine by itself.
I doubt it’s really hash, and it’s definitely not authentic Vietnamese food. But it turned out to be a tasty way of using up odds and ends.
