The spelling of whisk(e)y can be confusing and I think it's all a bit silly but people care about these things.
Whisky comes from Scotland, Canada, and Japan
Whiskey comes from America and Ireland
Multiple whiskies come from Scotland, Canada, and Japan
Multiple whiskeys come from America and Ireland
The short way to remember that is the countries with E's in their names, United States of America and Ireland, are spelled with an E in whiskey.
But as more countries begin making whisk(e)y, we'll have to revisit the question. There are already whiskies from India, Sweden, and Wales, all spelled without the E despite the Es in some of their names.
Did all that thinking make you thirsty? Me too! Here's a super easy, low-thinking whiskey drink made with Irish whiskey brand Paddy.
Feel free to substitute any blended Irish whiskey for Paddy. You can also substitute honey syrup (honey diluted in equal parts boiling water) in this recipe for easier mixing- just double the amount. For the bitters, you can try substituting a different brand of citrusy bitters if you have them. I used two dashes of grapefruit bitters and one dash of Angostura.
