Pear Yam Salad

In a saucepan, cook the yams for 8 to 10 minutes in boiling water just until tender. Do not overcook. Drain; set aside to cool. Core the pears and cut into chunks. Toss the pears with the lemon juice and mix with the cooled yams in a large bowl. Add the pecans, celery and raisins, mixing gently. In a small bowl, mix together the mayonnaise, honey, ginger and salt. Pour the dressing over the yam-pear mixture, mixing gently to coat the salad. Serve immediately or refrigerate.
