Combine splash of water and sugar in a shaker, stir to dissolve. Add the rum and egg yolk, shake everything without ice, pour into a glass. Fill with hot water. This recipe is a reduction of a fussy old English drink that involved ale, red hot powers, and lots of related process to something that can be executed on demand for a single serving at a bar. Apparently a post-1862 innovation.
