Nose
Warm whisky and lemon peel rise first, with nutmeg reinforcing the familiar sling/toddy winter register.
Palate
This is a direct hot sling, less elaborate than punch but still more dressed than a bare spirit-and-water serve because the peel and nutmeg keep it in the mixed-drink world.
Finish
The finish is warm, malty, and lightly spiced.
Summary
A straightforward hot Scotch sling preserving the warm-service strand beneath later whisky classics.

Hot slings matter because they preserve a pre-cocktail service grammar that continues to coexist with more modern forms. Johnson keeps that strand alive even in a book otherwise moving toward twentieth-century standardisation.

This is a good example of the difference between hot sling and hot whiskey service: the sling remains a mixed and dressed drink, not just a plain pour lengthened with hot water.

The Complete Buffet Guide by V. B. Lewis (1903, p.68) — Hot

1 piecelemon peel — lemon peelacid
0.5 wine-glassScotch whisky base
0.5 glasswater — boiling waterdilution
nutmeg — nutmegother
0.5 lumpsugar — sugarsweetener
  1. Add the Scotch whisky, lump of sugar, and lemon peel to the glass.
  2. Fill the glass half full with boiling water, grate nutmeg on top, and serve.

Garnish: Lemon peel and grated nutmeg

Nose
Hot Scotch, peel, and nutmeg make the aroma more aromatic than the plainer skin branch.
Palate
This version is useful because it sits right on the border between sling and skin, preserving how porous those hot-service categories remained in practice.
Finish
The finish is warming, smoky, and peel-scented.
Summary
A hot Scotch sling from the overlap between the sling and skin branches.
