Almost anybody with more than a six pack of Bud in the fridge has acquired the oddball cocktail ingredient, used for one mixed drink but otherwise lies inert on the shelf, mocking them. If you’ve got a bottle of Kahlua, you can make a White Russian, and….. hmm… what else? The same goes for nonalcoholic drink components like syrups – Some article has a drink recipe calling for cinnamon-blueberry-bacon syrup which sounds yummy, and look, a recipe! So you make the syrup, it taste great, but after showing it off in a few rounds of the cocktail for friends, you’ve still got a half liter of the cinnamon-blueberry-bacon syrup left over. Now what?
My bar counter top and refrigerator is overrun with experiments with leftovers. Pineapple Gomme syrup? Check. Banana Infused Jameson Whiskey? Yup. Apple-cinnamon shrub? Indeed. Black-tea infused Smith and Cross – Bingo. Many of the brain cells I devote to improvising cocktails is spent trying to match up my bar of misfit ingredients with new ways to use them.
The experiment so far that’s given me the biggest challenge is the Porter Reduction Syrup I used in a previous blog post, Reverse engineering a cocktail: The Cup Of Awesome. While I deeply enjoy the Cup of Awesome, I can’t make it too often or I’ll grow tired of it. And unlike a fruit based syrup that’s relatively easy to imagine replacing an existing ingredient in a favorite cocktail, a heavy, beer based syrup stands out in the field by itself. It’s not similar to a whole lot else, thus the challenge.
The other challenge with the Porter syrup is it’s intense flavor. Your choice is to either let it dominate the flavor profile of the drink (like in the Cup of Awesome), or pair it up with something that also has a powerful flavor and adjust the ratios so that neither flavor wins out. As you may have seen in prior posts, I’m big on categorizing things, and one of the classifications I frequently fall back on is robust, full-bodied flavors – flavors that you’ll always pick out regardless of what else is going on. Some of my go-to base spirits in this category are:
- Smokey Scotch (Islay)
- Overproof Jamaican Rum
- Blackstrap Rum
And as accent ingredients:
- Fernet Branca
- Allspice Dram
Tonight I went through my lists, mentally pairing the Porter Syrup taste with the base spirit taste:
- Porter and Smoky Scotch? Maybe…
- Porter and Mezcal? Doubtful
- Porter and Smith and Cross Jamaican rum? Not sure.
- Porter and Blackstrap Rum? Hmm… This sounds interesting.
So Porter and Blackstrap rum it was. Blackstrap rum is a crazy uncle in the rum world. It’s made from blackstrap molasses, which is the lowest grade of molasses – what’s left after nearly all the sugar has been removed from sugar cane juice after multiple boilings. The crystallized sucrose becomes table sugar and other products. The molasses is what remains. The only generally available Blackstrap rum available here in the U.S. is from Cruzan. It’s very dark with a strongly molasses flavor and cheap. Not at all a sipping rum unless you’re a pirate. It’s usually used to add color to Tiki cocktails as the rum float. However, given that we’re trying to find a mate for our intensely strong and dark syrup made from reduced Porter beer, it doesn’t seem so crazy.
Now, how much of each ingredient? Since the Porter syrup is very sweet I don’t want to use too much, so my first stab is a 3:1 blackstrap/syrup ratio. With just those two ingredients you have something roughly akin to an Old Fashioned (whiskey, sugar, bitters), but from very much the wrong side of the tracks. The drink could work with just that. However, the egg white in the Cup of Awesome adds a nice texture to it, and works here as well, in addition toning down some of the sweetness from the Porter Syrup. While you could go 4:1 rum/syrup, the Porter flavor would fall too far into the background for my taste.
- 1.5 oz Blackstrap Rum
- .5 oz Porter Reduction Syrup
- .5 oz egg white
In a mixing glass, whip the egg white with a small hand frother/mixer until it’s very foamy. Add the rum and syrup. Stir for 30 seconds, strain into a chilled coupe. Normally cocktails with egg-white call for extreme shaking rather than stirring. However, shaking dilutes this drink too much. Regarding the frother, get a decent solid blade like BonJour makes rather than the cheap $5 spiral whisk versions. It makes a big difference in how frothy your egg-whites get.
The “Big Picture” message here is that cocktail recipe creation isn’t necessarily some divinely inspired zen wisdom.It’s often just a matter of iterating over flavors and ingredients on hand, mentally mashing together in your head, then trying out the ones that don’t instantly seem like a bad idea. Kahlua and St. Germain anyone?
