In the comments, Whit writes to ask,
I want to use my pretty little Iittala glasses for something on Oscar night–but I never know what kind of drink to serve in them. I guess they are for cordials or vodka shots as your quote said below. What could I serve in my adorable glasses that would just be a way for me to show them off before, after, or along with the real drink of the evening–the martini?
I confess, Whit’s a friend of mine (but I didn’t prod him to leave a comment, I swear!): I’ve seen his cordials glasses and they are adorable. It’s because of them that I know the what Iittala cordials look like in the first place… slender, small tumblers rectangular with a slight flare, not the tapered or rounded shape that’s common. But that’s almost secondary to the larger question: what can one serve in small cordials glasses besides cordials? Is there anything fancier just than pouring some sherry?
What immediately came to mind is the pousse-café, which is the name of a layered cordial drink. It’s based on the idea that different liquors have different specific gravities: water with sugar dissolved in it is heavier than plain water, which is heavier than alcohol. Lower proof, sweeter liqueurs will sink in the glass, more alcoholic, drier liqueurs will rise.
The layering technique is called “floating.” Pour the first layer. Then on the back of a small spoon (this minimized disruption of the layers below), gently pour another thin layer. Wait a few seconds until the layers settle. Repeat with as many layers as you like, taking your time. The result is a lovely banding of different colors and flavors. Here’s a simple and tasty one I created with grenadine, maraschino liqueur, Chartreuse and cognac:
This is definitely Advanced Bartending territory, or at least Intermediate. Not only is there the technique of floating to master (not all that hard really), the drink requires having the appropriate liqueurs on hand. From heaviest to lightest, here are some possibilities:
Crème de Cassis / Grenadine
Anisette
Kahlua
White Crème de Cacao / Maraschino Liqueur
Crème de Menthe (Green or White)
Blue Curacao / Galliano
Amaretto
Tia maria
Drambuie / Frangelico / Orange Curacao
Campari / Yellow Chartreuse
Midori / Apricot brandy / Cherry brandy / Peach brandy
Cointreau / Brandy / Sloe gin / Kummel / Benedictine
Green Chartreuse
Southern Comfort
Kirsch
Cognac
Cream
Ingredients listed horizontally are comparable in density. The further apart in density, the clearer the layers will separate. There are longer lists that include the color and specific gravity of each. Or you can check out vintage recipes that will list strange-sounding combinations with obscure ingredients like crème de violette.
For the most part I avoid these recipes. They’re designed for visual impact, not flavor. Certainly, you want consider different colors in layering a pousse-café; the drink is all about the presentation after all. But don’t make your guest (or yourself) suffer through a Midori, Frangelico and Cream combination because it looks pretty. Pick liqueurs that go well together.
If in doubt, stay simple. Kalhua, Crème de Cacao and Brandy. Or Drambuie, Apricot Brandy, and Benedictine. You don’t have to have tons of brightly colored liquors or expensive, designer glassware to make a pousse-café. A small cordial of just Cointreau with a fine brandy layered on top is elegant, balanced and nearly unbeatable.
