Place the vanilla beans or vanilla bean paste, the egg yolks, and the powdered sugar in a stand mixer. Alternately, use a hand mixer. Either appliance should be fitted with the whisk attachment. Beat the ingredients until creamy, about 5 minutes.

Add the condensed milk and white rum and beat until combined.

Transfer the mixture to a double boiler. If you don’t have a double boiler, place a smaller saucepan inside a slightly larger one that is filled with one inch of water. Place the mixture in the smaller pan to heat.

Beat the mixture over medium to low heat with a whisk attachment until thick and creamy. About 6 – 8 minutes. Be careful not to let the mixture boil.

Transfer the egg liquor to a bottle, seal, and place in the refrigerator until ready to drink.

Yield: Makes about 2 cups
