Clarified Gin and Juice

This is part of my series of recipes from Liquid Intelligence. I’m going to make all of them, which you can see here.

One of Dave Arnold’s recipes I’ve been making for awhile is the Gin and Juice. I was able to find videos of it on the web, and piece together the process from his podcast. But there’s a recipe for it in Liquid Intelligence so I thought I’d make it for my family Christmas party. Apologies in advance for my worse-than-usual photography, but I was batching two cocktails and getting ready for a party.

This recipe isn’t particularly difficult, and is a great introduction to clarification. You can do it a few ways. If you don’t care about yield and just want a fast, easy product, you can use Pectinex/Chitosan/Keiselsol clarification (more on that later) and just wait a few hours for the solids to separate. Your yield is relatively low though without a centrifuge, on the order of 50-75%.

If you don’t mind waiting a bit longer, agar clarification is the way to go. That’s what Dave recommends, so for this post that’s what I did. It’s not that much more labor than the Pectinex/fining I mentioned, and the yield is much higher. I think I got over 90%. You’ll see my picture of the solids raft left at the end, that was all that didn’t make it, and some of that was agar.

Here’s the process:

Step 1: Juice the grapefruit.

I can’t remember how many I used, but it was most of a bag from Sam’s Club. (Sorry, I’m in Akron, we don’t have Costco yet.) I ended up with about a liter and a half.

Step 2: Hydrate the agar

Divide the grapefruit, 75% in one batch (assuming it’s room temperature) that you’ll set aside, and 25% in another, that you’ll put into a pan. In my case,  I set 1.1 liters aside, and put 400 liters in the pan.

Measure out agar to 2g per liter, so in this case I used 3g. (I use Telephone brand packets. I ran out of this packet and had to go to the Asian market, all for 0.4 grams!)

Whisk it vigorously into the small portion of juice. Place the pan on the stove, turn the heat to high and let it come to a boil, whisking frequently.

When it boils, put a lid on the pan, drop the heat, and let it simmer for a few minutes.

Step 3: Temper the juice and set.

Pour the room temperature juice into the hot stuff, stirring vigorously. You want to avoid the mix gelling at all, which might happen if you did it the other way around, or didn’t boil enough of the juice.

Pour into a bowl and set over an ice bath to chill. Don’t agitate it at all. No stirring. Just wait for it to gel all the way through.

Step 4: Freeze

Place the bowl into the freezer, and let sit overnight.

Step 5: Thaw

Place the frozen brick of agar in a strainer and let the liquid drip through. It starts off like this:

and ends like this:

Step 6: Filter

I ran what was left of the juice through a Chemex to suck up a little bit of particulate matter that got through.

Step 7: Mix ingredients and chill

I mixed up enough of Dave’s recipe to make about 1.65 liters, since I was carbonating in a 2 liter bottle. That worked out to a batch of ten. The recipe is:

590ml gin

800ml agar-clarified grapefruit juice

220ml water

40ml simple syrup

20 drops saline solution

I funneled them all into a 2 liter bottle, and put the bottle in the freezer. I shook it every 15 minutes or so, so it would chill evenly, and had to be careful to pull it out before it froze (the ABV is low enough that I think it would).

When it was ice cold, I carbonated with my homebrew rig.

Step 8: Play Snoop Dogg on radio and pour into champagne flute
