Nose
Warm whiskey rises plainly, with optional lemon brightening the edge.
Palate
It is closer to the plain hot punch tradition than to the more ornamented bowl punches, showing Irish whiskey service in its most direct social form.
Finish
The finish is warm, grainy, and gently sweet.
Summary
A direct hot whiskey punch that preserves the ordinary but important grammar of Irish warming service.

Miller's note that this is the genuine Irish beverage is source-side positioning worth keeping. It helps us track not just formulas, but claims of authenticity within late nineteenth-century bartending culture.

The order matters: dissolve sugar first, then add the whiskey. This is exactly the kind of hot-punch rule Miller foregrounds in his introductory note.
