If you want to mix up this iconic beast, you'll need a plethora of ingredients including the surprisingly powerful Cherry Heering (some renditions rocking 100 proof alone) and Benedictine, Gin, Grand Marnier, Angostura Bitters, with a sweet bomb of Lime, Grenadine, and Pineapple.

The Classic Singapore Sling
1.5 oz Gin
1/2 oz Cherry Heering
1/4 oz Grand Marnier
1/4 oz Benedictine
1 dash Angostura Bitters
1/2 oz Lime Juice (unsweetened)
1/2 oz Grenadine
4 oz Pineapple Juice
Shake with ice and pour into a lovely tall glass.

TASTING NOTES
+ Frothy
+ Sweet, and fruity...to be expected
+ Hard to trace the gin.  That's kind of the point.
+ Booze is hidden.
+ Hmm.  Let's talk about it.

My trouble with this particular classification of drink is that its core purpose is to HIDE the alcohol under juice.  This also cuts the strength, mind you, but to my particular tastes that have now evolved beyond the backwoods grain alcohol bathtub punch drunk masses knee deep in the frat houses of yore...the drink falls remarkably flat for me.
With hints of orange, and grenadine, the star is the Pineapple.  It can't not be, as is the nature of its volume.  The lime cuts the palette well, but the Gin and the Heering are barely there.  There's no subtlety to this taste.  No personality.  
  And as is par for most drinks of this caliber, this is one strong drink.  And, unfortunately, it tastes about the same as any Hurricane or Zombie.
Which, to me, is just a tad...boring.

There's a part 2 in here somewhere, but for now, I'll go make something that has something to say.

See you at the Bar,

1/2 oz Kahlua
1/2 oz Peppermint Schnapps
1/2 oz Bailey's Irish Cream
Shake with ice in a beautiful shaker and strain into a glass.

TASTING NOTES
+ Trippy Chocolate Milk
+ Hard to go wrong with these flavors.
​+ Really delicious.

1 oz Apricot Brandy
1 oz Curacao
1.5 oz Lime Juice

TASTING NOTES
​+ Coming from a guy who really can't stand Brandy...
+ ...THIS IS FREAKING DELICIOUS
+ No joke.  That is one tasty little drink.
+ It's the Lime that's the star here.
+ Usually the Brandy burns too long, and here the Lime juice obliterates that problem.
+ the Curacao only elevates the experience.
+ ...time to pour another...

1/2 oz Kahlua
1/2 oz Bailey's Irish Cream
1/2 oz White Creme de Menthe
Shake in a lovely shaker with ice and strain into a glass.

TASTING NOTES
+ Lingering burn from the Creme de Menthe White
+ Sweet, but doesn't last long.
+ Oddly enough...I'm getting a strange aftertaste of CELERY.  WTH.

Enjoy your time at the end of watch.  Whenever it suits you.

Tonight's special comes to you in the form of a simple request.
  "I'd like a Red-Headed, but without the Red-Headed."

To that, you'd probably first check your blades, then the other patrons.  An assassination attempt is certainly imminent.
  And then the barkeep sighs, and pushes your way a familiar red potion.  

This is known to the worlds forgotten as a ZONKER.  Strong, sweet, and terribly tasty.
To mix a Zonker, you'll need some Vodka, fruity liqueur, Amaretto, and Cranberry Juice.
1 oz each of Vodka, Triple Sec, Amaretto, and the Cranberry Juice get tossed into a shaker with ice, and a few shakes later, strained into a glass to enjoy.

TASTING NOTES
+ It's certainly fruity, but...
+ The triple sec overpowers like nobody's business.
+ Miraculously, this isn't fruity ENOUGH.
+ There's too much of that weird cough medicine vibe.

This is when The Lady interjects with her own rendition.  Consider instead the following:
1 oz Vodka
1 oz Triple Sec
1 oz Amaretto
2 oz Cranberry Juice

And suddenly, this is pretty lovely.  Add in 1 oz of Peach Schnapps, and you're good to go.  For my Lady, one shot's worth is enough here, as it is effectively a dessert at this point.  You'll sip down six before you notice the buzz, or suck down a high ball glass of the stuff and feel it for hours.  
It's simple, sweet, and terribly fruity.

Imbibe Responsibly at my table.

Today we visit two monsters.  The first is the bane of every Chinese restaurant.  A beast of liquor and a powerhouse of hidden flavors, perfect for knocking you on your butt and doing little else.  This is, of course, the Zombie.
  A cornucopia of rums and juices, most complimentary pairings are covered by the sweet and sour, making the effect insidious and arresting.

THE ZOMBIE
1 oz Light Rum
1 oz Dark Rum
1/2 oz Triple Sec
Dash of Grenadine
2 oz Orange Juice
2 oz Sour Mix
Shake, then top with 1/2 oz of 151 Rum

TASTING NOTES
+ As expected, this is smooth and sweet.
+ And it will knock you right on your butt.
+ Fruity flavors blend well with the two rums.
+ ...but something is missing.

I propose another approach.  Something to augment and deepen those fruity flavors.  The effect is just as powerful, and way more yummy.

THE SKELETON GUARD
1 oz Black Rum
1 oz White Rum
1/2 oz Triple Sec
Splash of Simple Syrup
4 dashes of Angostura Bitters
2 oz Sweet and Sour Mix
1 oz Jaegermeister
1 oz Apple Mango juice

TASTING NOTES 
+ So smooth and sweet.
+ ...which is dangerous, because I want to guzzle it down.
+ This will mess you up for a long while.
+ Simple over grenadine works really well.
+ The bitters provide just enough difference to keep us from spilling over into too much sweet.

...This drink will mess you up.  I mean it.  One and done.  Take a swig, drink it down, then snuggle up with your favorite pet and bad anime and enjoy for the next 3-5 hours.  Woof.

Imbibe responsibly.  And be careful about what necromancy brings you back from the dead.
