6 egg yolks slightly beaten
1 can condensed milk
1 can evaporated milk
2 c. sugar
1 c. water
1 c. rum
1 tsp. vanilla

Make a syrup with the sugar and water. Allow to cool. Mix eggs, condensed milk and evaporated milk thoroughly. Add syrup, rum and vanilla. Strain.

Make sure these are "pure", as some brands contain "fillers", and those won't work.
