Coquito

Cocktail Ingredients:

2 egg yolks, beaten
1 (12 fluid ounce) can evaporated milk
1 (14 ounce) can cream of coconut
1 (14 ounce) can sweetened condensed milk
1/2 cup white rum
1/2 cup water
1/4 teaspoon ground cloves
1/2 teaspoon ground cinnamon
1 teaspoon vanilla extract

Instructions:

In 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.
