A longer cousin of the common string bean, Chinese long beans add color and flavor to chef Pierre Schaedelin's braised short ribs from "Martha's Entertaining."
Preheat oven to 350 degrees. Prepare an ice-water bath. Blanch beans in a pot of boiling salted water until just tender, about 4 minutes. Using a slotted spoon, transfer beans to ice bath until cool, then drain and pat dry.
Make bundles by wrapping six or seven beans around your first three fingers. Arrange on a parchment-lined baking sheet. Drizzle with olive oil, and season with salt and pepper. Cook just until heated through, about 10 minutes. Serve warm.
