If you want that store-bought broth to taste more like it was homemade, all you need is a little miso. Photo by Crystal.
Miso is a Japanese seasoning made from fermented soybeans, salt and the koji fungus. And it is packed with savoury umami flavour. If your store-bought broth isn't quite cutting it, Riddley Gemperlein-Schirm at Food52 recommends you add a tablespoon of miso or miso paste. Bring the broth to a simmer, whisk in the miso and it will taste great. Just make sure you don't let it come to a boil. The high heat might kill off the miso's aroma and undo some of the flavour boosting. Also, keep in mind that miso is pretty salty, so you might want to use low-sodium broth.
