My father's name was Josef, but my mother lovingly called him Seppo. So in memory of my dad I am posting his recipe for Eggnog.

Seppo's Eggnog

beat until stiff
12 eggwhites

beat in
1/2 c sugar

beat until light (about 3 min.)
12 eggyolks
add 1 c sugar
and 1/4 t salt

combine all above and stir thoroughly

add 1 quart heavy whipping cream, whipped
(make whipped cream before adding)
1 quart milk
1 quart brandy
beat well
add 1 c dark rum, stir

makes about 2 gallons but settles to 1 gallon (if you give it time). Keep in cool place at least a week to smooth out.
