Whiskey made in Ireland. There are several types of whiskey common to Ireland: Single Malt, Single Grain, Pure Pot Still and Blended Whiskey.

Whisky made in Scotland, divided into four distinct categories: single malt, vatted malt (also called "pure malt"), blended and single grain. Malt whisky must contain no grain other than malted barley and is traditionally distilled in pot stills. Older recipes typically call for strong, smokey single malt Scotch. By the early 1900s blended Scotch was more often used.

Many 19th century recipes specifically called for white sugar, which is more refined and preferred over browner sugars. But modern white sugar is probably too refined, making raw cane sugar the best, easily available choice.
