I'm not Irish, but I've done that before. Not to be sneaky or impolite, but if the host of the party is busy or having a really great time, sometimes it makes more sense to quietly leave rather than disturb the host.
This is particularly true if it's a big party.
I've been in the situation where I've hunted for the host to say goodbye, and eventually I decide that I'll never win the hide-and-seek, so I leave and then contact the host the next day to say thanks for the great party.
Anyway, the folks at Smirnoff created a cocktail called the Irish Goodbye, which involves dropping a shot of Smirnoff Kissed Caramel vodka into a class of hard apple cider.
While that sounds like it could be good, I decided to spin it my way. I kept the Kissed Caramel (hey, they sent it to me, I figured I might as well use it) and I kept the apple flavor, but instead of hard apple cider, I decided to use a rustic apple juice - not the clear stuff that's all sugary, but a more substantial juice with great apple flavor.
Agave nectar or honey, as needed
Cinnamon, as needed
1 ounce Smirnoff Kissed Caramel vodka
Apple juice, as needed
Use a clean finger or a small pastry brush to coat the outer rim of the glass with a thin coat of of the agave or honey - this is just to create a sticky surface, so a light coat is all you need.
Sprinkle the cinnamon over the coating to crate a dusty rim. If you prefer a sweet rim, you could use cinnamon sugar, or plain sugar instead.
Fill the glass with ice, then add the vodka and apple juice. Stir and serve.
Smirnoff occasionally provides me with products to make cocktails on my blog. Cheers!
