Tips & Notes

Pro tips

Use freshly boiled water for maximum heat and proper dilution; let it cool slightly if serving in delicate glassware.
If flaming, use high-proof whiskey and perform over a heat-safe surface away from flammable materials—this is an advanced technique.
Pre-warm your serving glass with hot water before pouring to prevent thermal shock.
The 1:1 whiskey-to-water ratio is traditional; adjust for strength preference or add honey/sugar syrup for a sweeter variation.

Substitutions

Old Mr. Boston whiskey → any bourbon, rye, or blended whiskey (adjusts flavor profile slightly)
Boiling water → hot water with honey or simple syrup (adds sweetness)

Storage & make-ahead

This is a cocktail meant to be served fresh and consumed immediately after preparation.

Equipment

heat-safe mug or Irish coffee glass · metal mixing cups (if flaming)
