Hey all :)

I'm looking for advice and suggestions towards what I should add to my home bar. I've recently got quite into mixing cocktails and have bought a couple of books on it but every time I browse through them new drinks jump out at me and I think "Oh, I'll try that... no wait I don't have any -insert odd booze-"

So what are your favourite alcoholic beverages? I can't never really decide what to buy at the time and end up restocking on old favourites.

I already have some of the basics and some personal favourites:

White Rum
Dark Rum
Coconut Rum
Peach Schnapps
Blue Curaçao
Sour Apple liqueur
Toffee Liqueur
Banana Liqueur
Cherry Liqueur
Baileys Irish Cream

What should I add?
