Add leeks and garlic, and cook until tender. Add flour, stirring until smooth. Then cook 1 minute, stirring constantly. Gradually add broth and wine; cook over medium heat, stirring constantly, until mixture is thickened (about 4 minutes). Stir in half-and-half, crab meat and salt and pepper. Garnish with sliced leeks. Serves 6.
