Bring broth to a boil. Return pan to heat. Add 1/2 tablespoon to pan. Break pasta in thirds, add to pan, and saute; the pasta will brown somewhat, and some strands may turn light. After 3-4 minutes of stirring, add 2 cups boiling water to pan. Turn heat to high and boil pasta. As broth evaporates, add additional broth in 1/4 cup increments, testing pasta for doneness.
