1     apple (cored and cut into large pieces) 
1     stalk celery (diced) 
1/4   cup raisins 
1/4   cup chopped nuts 
1/2   cup grapes 
4     tablespoons mayonaise 
1/2   Tablespoon sugar 

Mix everything together. Taste. If you feel you need more of anything - just add it.  Or if you feel there is too much of one thing - put in less.
