What's the best broth for vegan risotto?

To make risotto vegan, all you have to do is axe the cheese and butter (and possibly the wine) and use the following vegan broth instead of chicken broth. Try using miso broth. So instead of vegetable broth for risotto, you can turn to miso broth (either without dashi or with kombu dashi, which is vegan-friendly and uses dried kelp, per Just One Cookbook). They recommend using ⅓ cup of white miso with 3 cups of water and 4 cups of vegetable broth, while TheKitchn suggests 2 tablespoons of white miso paste with 6 cups of water. So it's up to you whether you'd like to combine miso paste with vegetable broth or use it on its own with water.
