1 qt. commercial eggnog
1 pt. fresh orange juice with pulp
1 12 oz. can orange juice concentrate, thawed
1 qt. milk

In punch bowl, mix egg yolks and sugar.  Add whipped whipping cream,

Fold egg whites into eggnog mixture just till smooth.

Notes:
We double this recipe in my grandmother's LARGE punch bowl for my family's
Christmas gathering of about 70.  Of course, most of 
the kids (about 1/2 of the 70) don't drink it but there's never a bit left,
so I would say this recipe serves about 20 with plenty left for seconds.
