Solid Liquids: Campari Syrup

In the last post in the Solid Liquids project, I used dehydrated Campari to make a non-alcoholic Campari & Soda.

Then it occurred to me that for that purpose there was no need to dehydrate the liqueur completely. I could just burn off the alcohol and have a non-alcoholic syrup.

So that's what I did. I filled a pot with Campari and took its temperature with a candy thermometer when heating it. Alcohol boils at 172F as opposed to 212F for water, so I tried to keep the temperature between the two.

It started to bubble around 175 and I could smell alcohol vapor. It began boiling around 183F. When it got to 189F it began to look thicker, as plenty had boiled off.

After an hour total I cooled the liquid to check the volume and found it to be reduced by 50 percent. And since the alcohol content of Campari is 24 percent alcohol hopefully all the booze and some of the water burned off as well.

After cooling and storing it, I made another non-alcoholic Campari & Soda. I added about an ounce of Campari syrup to about 3 ounces of soda water.

It's good, probably better than the powdered liqueur version. But campared with regular Campari & soda, real Campari still tastes better. Again the real deal has more of an orangey flavor, so the non-alcoholic version can use an expressed orange peel added to it.

I'm guessing that the volatile citrus orange (oil?) in Campari burns off in the cooking and that's why it's not present in the syrup/solid version.

So: What else should I use this Campari syrup for?

Update: I just remembered that I saw Campari syrup on the menu at Nightjar in London. I'm not sure if their syrup is the same thing or something else, but it's in two drinks from the summer menu (forgive the funky formatting, it's their font):

Solid Liquids: Dehydrating Liqueurs in the Microwave

In the process of making powdered liqueurs for future use, I've been trying to figure out the best method to get liquids into solids. I'll be comparing the microwave to the oven to the food dehydrator, using Campari as my first liqueur in all of them.

In today's post we'll look at using the microwave. As I learned the hard way, what you don't want to do is stick a liqueur in the microwave and turn it on high. It fizzes, splatters, and burns.

So I attempted to dehydrate liqueur using a low-power setting. In the process I learned something about microwaves, or at least the microwave that I own: Lowering the power doesn't actually lower the strength of the microwave energy, it only changes the length of time it blasts that energy into your food.

So at the lowest power setting (10 on my microwave), it blasts the liqueur with microwave energy for 10 percent of the time, or for 3 or 4 out of every 30 seconds. The rest of the time it's just turning on the plate. The "defrost" setting is level 30, which should tell you how low the setting is.

The One-Shot Method

Because I don't want to stand around the microwave pressing stop and start, I tried to find the setting that would allow me to cook down a liqueur to a solid.

After several tries and lots of hot boiled Campari I determined that I couldn't microwave on any power setting higher than the lowest setting of 10. After just a few seconds the liqueur would start to boil rapidly, then it settles down in the remaining 27 seconds. However, after it cooks down nearer to the end (all the alcohol should be boiled off, but the water is still trapped in the syrup) it seems to boil faster, and overflows and splatters after only the 3-4 second heat interval.

Thus it seems that my microwave is too powerful to effectively reduce the last part of the liquid liqueur to a solid.

The closest I've come (so far) to making this effective is cooking it on the lowest power setting for 60 minutes (which reduces the volume by half, close to the final volume of syrup) then finishing the drying in the oven at 170 degrees Fahrenheit as this is low enough that the syrup doesn't boil over.

However, at least in initial experiments, it takes a very long time to bake off the final water – more than 5 hours. And in this case, I may as well just stick it in the oven at 170 degrees Fahreinheit over night.

The Babysitter Method

As the 'set it and forget it' method of programming the microwave proved ineffective, I thought I'd try the hard way. I put the same 2 ounces of Campari in the microwave and heated it for short bursts until it boiled. Then I'd stop, wait for it to settle, and hit it again. The point was to prevent overboiling and burning.

Don Lee reported success with this method, using short bursts at the beginning and end of cooking, and longer cooking in the middle.

I begun with 20 minutes cooking time on the clock, then kept pausing the heating as the boil became violent. Initially I'd do it standing there babysitting the thing, but then as it was taking forever I'd send emails and such in between heating bursts, allowing it to cool more.

Unfortunately, this method allowed me no long bursts of cooking – it kept boiling over at 10 seconds maximum. More than 85 short bursts over several hours later, it finally chrystalized, though there wasn't all that much of it left.

In conclusion, with my microwave and using Campari anyway, this method is a pain in the butt and not worth the effort compared with setting the oven on a low temperature and letting it cook down overnight.

Solid Liquids: Dehydrating Liqueurs in the Oven

In the process of making powdered liqueurs for future use, I've been trying to figure out the best method to get liquids into solids. I'll be comparing the microwave to the oven to the food dehydrator, using Campari as my first liqueur in all of them.

In today's post we'll look at using the oven. Following the suggestion of Don Lee on this eGullet thread, I purchased silicone cupcake cups to experiment with. They can be used in the microwave or oven and are easy to clean.

In all of my oven experiments, the procedure was the same. I filled the cupcake cup with 2 ounces of Campari, put it on a cookie sheet, and put it in the oven. Most of the time I cooked the liquid for 12-24 hours.

Dehydrating Campari at 140F and 170F (in separate trials), the liqueur would dehydrate and get clumpy. I'd then squeeze the cupcake cup a bit to break up the clumps and expose any wet spots so that it would dry completely. In the end I had a combination of powder and pebble-sized clumps of dehydrated Campari.

At 200F I had clearly reach some sort of candying state with the sugar. It looked like it was still watery with liquid, but on further inspection it was closer to a melted lollipop- very brilliant liquid sugar. On removal from the oven it formed a hard puck shaped like a Reese's Peanut Butter Cup.

At 250F the sugar burns a bit, becoming brown in color and smelling more like molasses. It also stays liquid and forms a hard puck in the bottom of the cupcake cup.

On tasting after grinding these with a mortar and pestle, I found that the 250F Campari tasted like brown sugar or molasses with a bitter Campari twinge to it. It wasn't nearly as bad as I expected but I am not sure how I'd use it. Campari gingerbread cookies, perhaps?

(Campari cooked at 200F vs 250F)

The 200F powdered Campari had a distinctly sharp bitterness to it. The 170F Campari powder had the best and most Campari-esque flavor of all, with that great Campari brightness still present and a balance of sweetness from sugar with the heavy bitterness there too. The 140F powder was also very good, but I prefer the 170 at least on this first experiment.

Another reason to use the lower-temperature Campari powder is that the others were harder to crush up (like crushing a lollipop instead of granola). They also seem to want to stick together. After crushing, they get clumpy. (I tried reheating at a lower temperature to see if it would stop clumping, but it just formed back into a blog and I had to re-crush it again!) Clumpy clusters are probably be fine for baking purposes, but not practical for rimming cocktail glasses.

Long story short: Oven at 170F worked best for me.

In the next post, we'll look at using the microwave to dehydrate liqueur.

Solid Liquids: Dehydrated Liqueurs on Cocktail Menus
I've spent some time researching powdered/dehydrated liqueurs online to see where and how they've been used. Turns out: all around the world. Below are the few I found.

It seems that for the most part these dehydrated liqueurs are used as a powdered rims on cocktail glasses, as garnishes sprinkled on top of egg white drinks, and in one case as a popcorn flavoring.
- Araka in Clayton, Missouri uses Campari powder to rim glasses.
- The bar Mea Culpa in Ponsonby, New Zealand, had the following drink on their menu: ANGEL DUST - Cherry & orange macerated Rittenhouse Rye, Liquore Strega, White creme de cacao, Benedictine foam, Campari powder
- This drink from Josh Pape of Chambar Belgian Restaurant in Vancouver, BC contains toasted cashews, gin, pink grapefruit cordial, sherry, apple juice, egg white, and has Campari powder on the rim.
- Eau de Vie in Sydney offered, according to this post, "The Countessa, a reimagined Negroni with Aperol, served up in an exquisite coupe, on the side a half time slice of orange, dusted with Campari powder and caramelized with a blowtorch behind the bar. "
- Val Stefanov of Ontario, Canada used dehydrated Campari to make Campari cotton candy.
- Tom Noviss of Brighton made a Campari powder-rimmed drink with 42BELOW Feijoa vodka, Xante Pear, Avocado, and other ingredients.
- Anvil in Texas used dehydrated Campari and Chartreuse crystals. They also used some on popcorn!
- Callooh Callay in London was using dehydrated Campari in a version of the Negroni.
- Der Raum in Melbourne used it on a tasting menu.
- At Elements in Princeton, New Jersey, they make The Skål! Cocktail with akvavit, Pedro Ximénez sherry, dry vermouth, lemon juice, and lingonberry preserves. Garnished with a rim of dehydrated Chartreuse.
What other drinks have you seen? Any other liqueurs besides Chartreuse and Campari?
