I need to get some Advocaat, which is made from egg yolks, brandy, and vanilla. Heather used to call it “egg nog liqueur,” which isn’t that far from the truth. I’m guessing it will be a dandy base for any number of creamy Christmas bevvies. I’m guessing Ginger snaps, Egg Nog variations, nutty drinks, &c. There is a Mexican cousin of Advocaat that goes by the name of Rompope.
