1 lg. lime Jello 
3 c. boiling water 
1 c. juice from pears 
1/2 tsp. salt 
2 tsp. vinegar 
1 lg. can pears, diced 
1 c. fine chopped pecans (or walnuts) 
6 oz. cream cheese 
1/8 tsp. ginger

Dissolve Jello in boiling water and add salt and vinegar. Pour 1/2 to 1 inch into a ring mold. Chill remaining Jello until syrupy. While Jello is cooling soften cheese using a small amount of milk and blend in ginger. When Jello is thick beat at high speed until it is very light and foamy. Add cream cheese and then fold in the pears and nuts. Pour this mixture into mold on top of the solid layer. Unmold on large round plate. Mandarin oranges mixed with coconut or a container of salad dressing can be put in the center.
