You can cook wild rice, as you can cook any grain, in plain water, and it will be delicious, letting the delicate flavor of the rice shine. Or you can use a diluted broth to cook the rice or other grains, which will infuse the grains with more flavor. I like to mix about 1 part low-sodium vegetable broth to 1 part water to cook grains. I think allows the grain’s flavor to emerge with a bit of a boost.
