Watermelon is a tricky fruit to tackle when wanting to use it in a cocktail. It’s mostly water, obviously, hence the name, about 92% and the rest sugar and not much else. The thing with watermelon that has always frustrated me when using it is the taste doesn’t transfer very well. Call me crazy but watermelon candy doesn’t taste a freaking thing like biting into a fresh cut watermelon. Juicing the watermelon is easy but the flavor only last about a day. So to make a watermelon concoction practical to serve behind the bar, somewhat cost effective, not that time consuming, and taste like watermelon is almost an impossible task… almost.
I had an idea in my head for a watermelon drink after some buddies and I cut one up and ate the whole thing. When you cut the melon in half what do you see? It’s round (like looking into the top of a glass) and has the look of a rim as well with the almost whitish rind. See where I’m going with this one… I set out to make a watermelon cocktail that looked like a watermelon in the glass.
Any other bartenders looking to experiment with watermelon keep in mind that the ENTIRE melon is edible. That might not mean much for experimenting with a drink but it does mean endless garnish ideas. Just throwing it out there.
The watermelon is in the same family as the cucumber. When choosing your melons, make sure they are pretty symmetrical and with a minimum or bruises and cracks. (Insert your boob joke here;-) You should also notice a melon fragrance along with a heavier than it looks feeling. What’s funny about this post is that we are creating a “seeded” looking watermelon but the best varieties (of the 50+) are the seedless ones? They are juicy, taste great, and of course have the added convenience of almost no seeds (okay, it’s not that funny.)
Like I said earlier the watermelon is a very hard ingredient to conquer. I started with something I felt would make sense; watermelon juice, some liquor, probably gin… maybe sake, and simple syrup or something. This got me closer than I expected for a first run and with a little tweaking, came up with something that was drinkable. The “look of seeds in the cocktail” idea is where I got carried away. I just got done messing around with some gelatin for a future post and figured I could make gelatin seeds? As I was experimenting though I toned down the gelatin a little bit so it doesn’t solidify all the way, just sort of gels. The basic idea is to get the gel into a squeeze bottle and then after the watermelon drink is made, squeeze in the black watermelon gel into the cocktail to get the look of seeds! Here’s the recipe and technique I came up with.
Watermelon Slushy
3 oz watermelon juice (puree, strain)
2 oz gin (I used Bombay dry)
3/4 oz simple syrup
1/2 oz nigori sake (nigori is unfiltered, milky white, and a touch of sweetness)
1/2 oz lemon juice
2 dashes peychouds bitters
11/2 cup very small ice
Combine all into a blender and puree, then pour into daiquiri glass and squeeze the “watermelon seed” gel into the glass creating a watermelon looking effect.
Black “watermelon seed” Gel
1 cup (8 oz) water melon juice
1 cup (8oz) sugar
1/8 teaspoon black food coloring (about 10-12 drops)
1 teaspoon powered gelatin
Combine all together into a pot and stir on low hear, put into squeeze bottle and refrigerate
Some tips on this, don’t over-heat the mixture. I found that getting the watermelon juice to hot will give it a kind of “dirt” flavor? I tried to reduce the mixture thinking I could get a more potent watermelon flavor… it didn’t work. When you are juicing your watermelon, I don’t know about a juicer, (mine broke, and I’m broke so I can’t get a new one yet) but when I put these chunks in a food processor then strained it I found that letting the juice sit in a container for an hour or two will settle any fine pulp. Another tip, the black food coloring is very messy and does not come out of clothes; a little goes a long way. Again I also fine strained this into the squeeze bottle using a metal small screen strainer just to get any extra pulp out and have a nice clean black gel to use in the drink.
I think watermelon could be the perfect medium for this if you messed around with the ingredients a little. I stopped trying to make a good drink and ended up spending my time messing with the gel. The gel has huge potential, if you had a lemon drink you could make the gel lime and on and on! It makes for more visual appealing drinks but there are drawbacks. The drink itself has to be slightly gelatin or blended, if you put the gel in a cocktail it just sinks to the bottom. The drink has to be a thick enough consistency to support the gel. Let me know what you come up with at your bar and I can assure you, I will be posting more in the future about using flavored gels behind the bar.
