Red miso is a stongly-flavoured fermented bean paste used at the heart of Japan’s cuisine. It is the saltiest of Japanese miso pastes, with bold umami flavours. You can afford to be a lot more sparing with red miso than white miso, but it's always worth tasting as you go.
Stir two tablespoons into a dashi stock to make miso soup, and then add seaweed, mushroom, noodles and tofu. This versatile ingredient works really well with other big flavours such as aubergine and red meat. Use in a marinade, or mix the red miso with a little soy sauce, sesame oil or mirin to make a glaze that explodes with flavour.
