The Remington (and sundry derivatives)

I was quite surprised by this relatively simple combination, which seems like it ought to be a well-known classic.  Granted, in proportion and construction, it's basically a Collins, but with some signature ingredients.

2 oz white whiskey (I used the local MN13 - good stuff!)
1 oz peach-brown sugar syrup
3/4 oz lemon juice

Combine in a tall glass over large cubes, stir, top with about 2 oz soda water, and stir again.

This version, the Remington, is quite a good one.  However, the simplicity of this combination makes it easy to swap out the peach for other flavors.  To wit:

For a Derringer, use cinnamon-brown sugar syrup.

For a Palomino, use vanilla-brown sugar syrup.

For a Caballero, use ancho chile-brown sugar syrup (yum).

How that's for a post - not just one cocktail, but 4 in one go!  Don't be silly, it's not cheating at all.
