- In the top of a double boiler, combine egg yolks and evaporated milk. Stirring constantly, cook over lightly simmering water until mixture reaches a temperature of 160 degrees F (71 degrees C). The mixture should be thick enough to coat the back of a spoon.
- Transfer mixture to a blender, and add cream of coconut, sweetened condensed milk, rum, water, cloves, cinnamon, and vanilla. Blend for about 30 seconds. Pour into glass bottles, and chill overnight.
