Whisk all glaze ingredients together.
Bring six cups water to a rapid boil in an eight-quart pot. Once water is boiling, add string beans and cover pot. Cook for six minutes. After six minutes, throw string beans into a bowl of ice water (or a strainer with running cold water).
Combine string beans with half of glaze (reserve the other half to use as a salad dressing). Let beans marinate so that the flavors meld. Serve at room temperature.
Notes:
Blanching preserves the great flavor of fresh string beans, holds the beautiful green color, and still gives you that wonderful string-bean crunch. Throw the beans in hot water to cook them briefly; then plunge them into cold water to “shock” them and stop the cooking process.
