• 2 c. baby arugula leaves, optional
• Handful chopped fresh chives or green onion tops
• Vinegary hot red pepper sauce, to taste
Put corned beef into a deep, large saucepan. Add cold water to cover meat by 1 inch. Add bay leaves, peppercorns, coriander seed and celery seed. Heat to a boil; reduce heat to very low, and cover. Simmer, turning meat occasionally, until a fork inserted comes out easily, about 3 hours. Add more water as needed to keep meat submerged. Let cool in the liquid. Transfer meat to container and add about 1 cup of the cooking liquid. Refrigerate, covered, up to several days. (Save the remaining flavorful cooking water for simmering vegetables such as carrots, cabbage and turnips for another meal.)
Meanwhile, cut potatoes crosswise in half. Cut each half into 1/2-inch-wide wedges. Place in a large microwave-safe bowl, and add 1 cup water. Cover tightly. Microwave on high (100 percent power), stirring once, until fork-tender, about 6 minutes. Drain.
