Rinse the rice and barley in a sieve, then drain and move to a 4-5 quart heavy pot.
Add water or broth and bring to a rolling boil.
Reduce heat to low and cook covered, about 45 minutes.
Remove from heat and let stand, covered, 10 minutes. Stir from top to bottom with a rubber spatula. Add salt and pepper to taste, or whatever seasoning you like. This is good served with veggies, soy sauce and a little butter too. Enjoy!
