Okay here’s the link to Christmas Passion the eggnog I’ve made on air a couple of times. Two additional furbelows were suggested by listeners:
The brandy/curacao/sherry eggnog marinated their yolks overnight in the booze, which would be well worth trying with any eggnog. She also whipped and folded in the eggwhites, which I consider optional with all eggnogs
Another caller used berry rum. A fruity eggnog can be brilliant. If you’re going this way, I’d suggest starting with brandy and Chambord which is the King of Berry liqueurs. (NB! Chambord is very low alk, and unlike most liqueurs will oxidize fairly rapidly. I suggest drinking withing 90 days of opening.)
