A tonkotsu (pork bone) soup broth that's easy to make at home. Even if you don't have a pork knuckle, you can make a tonkotsu flavored soup with ingredients you have in your refrigerator.
I bought ramen noodles for cheap, which was good, but it didn't come with soup, so I made it.
If you add beni-shouga red pickled ginger on top, it will be even more tonkotsu-like.
