The King's Ginger Liqueur
While the sunshine's likely to melt the NYC snow pretty soon, having a bottle of old-school winter warmer The King's Ginger Liqueur at hand wherever there's a big freeze should make things a bit more bearable. It was commissioned by Berry Bros & Rudd (who have been trading for over 300 years) for King Edward VII, and they still sell it today.
As well as loads of others in the know, my dad swears by it when things get a bit chilly in the mountains where he lives. On top of that, it's much cooler than Courvoisier.
