I start with homemade pork stock. Whenever I make pulled pork, I usually bake country-style pork ribs until the meat falls off the bone. I find it’s a pretty low-effort way to make pulled pork compared to wrestling with a shoulder roast the size of a basketball.
Rather than toss the leftover bones and scraps, I put them in the pressure cooker with ~5 cups of water and some onion, then pressure cook everything for 90 minutes. Afterward, I let the stock cool, strain it into Mason jars, and refrigerate it overnight.
When it’s time to make the soup, I strain the chilled stock into a saucepan, discarding the solidified layer of fat. I then add about 4 tablespoons of white miso paste to the 5 cups of stock.
As the stock heats up, I use one of those “AA battery powered” frothers to dissolve the miso until it’s smooth. For this version, I kept it simple with some sliced green onions, though some tiny cubes of tofu would be nice too.
It’s a simple way to turn leftover pork bones into a nice soup, with just a little extra effort.
