INGREDIENTS

2 tablespoons neutral cooking oil, like canola

2 garlic cloves, peeled and minced

1 ½-inch piece ginger root, peeled and minced

¼ teaspoon red-pepper flakes, or to taste

4 bunches of baby bok choy, approximately 1½ pounds, cleaned, with the ends trimmed

1 tablespoon soy sauce

1 tablespoon chicken stock or water

Toasted sesame oil for drizzling

PREPARATION.

In a large sauté pan with a lid, heat oil over medium-high heat until it starts to shimmer. Add garlic, ginger and red-pepper flakes and cook, stirring constantly, until fragrant, about 45 seconds.

Add bok choy and stir carefully to cover with oil, then cook for approximately 2 minutes. Add soy sauce, stock or water, then cover pan and cook for approximately 2 minutes more, until steam begins to escape from beneath the lid of the pan.
