Black rice, like brown rice, has a long cooking time. With the pink of the grapefruit and green avocado, the visual effect is startling and lovely. The flavors, however, are just as well served by any kind of rice, so don’t hesitate to use up what you have. Wild rice makes another lovely option.
Tip: If you don’t love eating the tough skin on grapefruit in salad, the best technique to research is how to supreme citrus.
