I asked my dad and he said he didn’t have a patent on the eggnog recipe, so here it is!

I have some translations to do. The original recipe is in US measures. I’ll do that first:

(need an empty 1 gallon milk jug)
1 cup (1/2 pint) each of:
Brandy
Blended whiskey
Rum (not light or dark* – not spiced!)
4-6 whole eggs – depends on how big they are, of course
2 cups (1 pint) heavy cream
1/4 to 1/2 cup sugar (I think I hit about the middle between the two)
1/4 teaspoon each cinnamon and nutmeg (may need a bit more, I didn’t have the measure written down! Dad said start with 1/4 and add more if you think it needs it. I’m making this next week so will see how much I use, but I suspect it is more.)

Beat eggs until smooth.
Add cream and a bit of the milk, doesn’t matter how much but not TOO much just yet!
Add all the alcohol. Add the sugar.
Stir until the sugar melts.
Add nutmeg and cinnamon.
Pour into empty 1 gallon jug, top up with milk until jug is full.
Shake well!

Okay, same thing but converted into metric! Doesn’t matter if it isn’t perfect, it’ll be tasty.

(need two empty 2-litre milk jugs)
237ml each of:
Brandy
Blended whiskey
Rum (not light or dark* – not spiced!)
4-6 whole eggs – depends on how big they are, of course
473ml heavy cream
4 to 8 tablespoons sugar (I think I hit about the middle between the two)
1/4 teaspoon each cinnamon and nutmeg (may need a bit more, I didn’t have the measure written down! Dad said start with 1/4 and add more if you think it needs it. I’m making this next week so will see how much I use, but I suspect it is more.)

Beat eggs until smooth.
Add cream and a bit of the milk, doesn’t matter how much but not TOO much just yet!
Add all the alcohol. Add the sugar.
Stir until the sugar melts.
Add nutmeg and cinnamon.
Pour into empty jugs, try to put the same amount in each, oh how fun, top up with milk until jugs are full.
Shake well!

* I can’t find ‘not light and not dark’ rum here; I just use the white or clear rum. I make it in a big mixing bowl and use a funnel. Yes, it’s a bit messy, but after two glasses you won’t care.
