Halve the bok choy lengthwise and rinse it well under cold running water, making sure to gently separate the leaves to get any dirt out.
In a large saucepan combine the broth, butter, soy sauce, ginger and garlic, and bring to a simmer over medium high heat. Add the boy choy, cover, and simmer for 7 to 8 minutes until the bok choy is tender but not mushy.
Remove the bok choy using tongs to a shallow serving bowl and return the pot with the braising liquid to medium high heat. Simmer until the liquid is reduced to 1/3 to 1/2 cup, then add the sesame oil and pour the sauce over the bok choy in the platter. Garnish with scallions if desired.
