It’s been just a bit longer than a year since Dave Arnold posted his method for clarifying lime juice with agar. This month’s Mixology Monday theme also happens to be lime. Further, my local grocery has good, juicy limes selling for a mere $.39 right now. Coincidence or synchronicity? Either way, it was clear what I must do for this month’s post.
Using agar clarification on juice is something I’ve been wanting to do for a while. My first experiments with agar clarification of coffee didn’t work nearly as well as using the more time-intensive gel-freeze-thaw method, but I’ve been overdue to try it with citrus. Click here for detailed directions. The basic idea is to hydrate agar in boiling water, whisk a larger amount of fresh lime juice into this solution, let set, and then filter through cloth. Sounds easy, right?
Well, it is easy. Today was my first time using this method on citrus and I was able to get a yield of 170 grams clarified juice from 200 grams of fresh juice, 50 grams water, and .5 grams agar. The only complication is that I was out of muslin through which to strain it, so an ill-fitting, never-worn linen shirt found constructive use as a filter. I probably could have extracted even more juice using Dave’s “massaging the sack” technique, but I was raised conservative. The resulting juice (right) is substantially clearer than juice that’s only been fine strained (left).
OK, neat, but who cares? That’s exactly what I thought as I was doing this today. But as soon as the first drops of clarified lime juice started dripping through the linen, I realized this was actually pretty cool. I could use this stuff in a traditional citrus cocktail, but I could probably stir it instead of shake it. The drink would look better and have better mouthfeel than it would with the air incorporated from shaking. As Dave says, “Clear drinks look more pleasing than cloudy ones, and have a better texture.” (The winning bartenders at this year’s 42 Below cocktail competition appears to have done something similar, as have a few others.)
This being a Mixology Monday hosted by none other than Doug from the Pegu Blog, the choice of cocktail was obvious: The Duck Fart. No, even better, the Pegu!
2 oz gin
1 oz Cointreau
.75 oz clarified lime juice
1 dash orange bitters
1 dash Angostura bitters
Stir over ice and strain into a chilled cocktail glass.
This is a slightly different recipe than I use for a traditional Pegu, but it tastes great. The cocktail (above) is much clearer than the shaken version:
The most interesting thing about this cocktail is that the flavor is so unexpected. You see a clean, transparent drink and think it’s all spirits, maybe vermouth, maybe some bitters. Then you taste it and surprise! There’s citrus all up in your face.
I also tried the clarified lime juice tonight in a Pendennis Club (meh) and a Last Word (nice, though I had to add a little extra lime). The technique isn’t practical enough that I’d use it all the time, but it’s definitely an idea that can be used to good effect in cocktails.
