Ginger is one of those spices that you generally don't need a lot of, but it's hard to buy just a small piece. That's why I like buy it in bulk and preserve it. I've talked before about preserving ginger in vodka, but juicing it and creating a syrup is another great way to make it last. This Lemongrass Ginger Syrup is convenient to use, and the sugar will help preserve the ginger for months.
I always have at lease one bottle of this in the fridge because it's great to use in marinades or as a flavorful sweetener for tea and coffee. I especially like mixing this with mint tea brewed from fresh mint leaves and a squeeze of lemon juice. Added to lemonade, the acid turns the ginger slightly pink, adding a spicy zing to the classic. I've even been drizzling this on homemade yogurt with some toasted oats for a delicious breakfast treat.
Of course the most obvious use Lemongrass Ginger Syrup is to make ginger ale by mixing the ginger syrup with lemon juice and seltzer water. It still has sugar, and can't be considered healthy, but it's certainly a better alternative than the commercial brands that are loaded with high fructose corn syrup. It's also nice because you can control the amount of sugar in each glass by reducing the amount of syrup you add. You'd be surprised at how little you can use and still have a great tasting soda. You could also add some poached aloe for a little extra fun. Aloe is very popular in beverages across Asia, and its neutral flavor will blend well with the spicy syrup.
For making lemongrass ginger syrup, be sure your ginger is fresh, and preferably young. As ginger rhizomes mature, they become drier and more fibrous making it difficult to extract the juice. Both types of ginger in the photo above are fresh ginger, but the one on the left is more mature than the one on the right. In the photo below you can see what a cross section of each looks like. The more mature ginger on the left is visibly more fibrous and the skin has gone from a yellowish pink to a brown color.
What you want to avoid, is ginger with beige papery skin as this means the rhizome has fully matured, making it nearly impossible to juice. Unfortunately, much of the ginger I've seen in US supermarkets is of this variety. Take a trip to your nearest Chinatown though, and you should be able to find crates of fresh young ginger for a few bucks a pound. You can pick up the lemongrass there as well. Then you'll be all set to make lemongrass ginger syrup, and probably a bunch of my other recipes if you shop like I do!
- 570 grams fresh ginger
- 3 stalks lemongrass
- 2 cups water
- 6 cups granulated sugar
- Thoroughly wash the ginger. You don't need to peel it, but break off any hanging pieces as dirt sometimes gets trapped between nodes. Roughly chop the ginger and lemongrass and add it to a food processor along with the lemongrass and 2 cups of water. Process until the mixture is pureed, scraping down the sides a few times with a spatula.
- Line a 2 cup liquid measuring cup with multiple layers of cheese cloth, or a single layer of fine-mesh muslin and scoop the ginger mixture onto the cheese cloth; you'll probably need to do this in batches. Gather up the edges of the cloth and twist the edges towards the bulge of ginger to wring out as much liquid as you can. Discard the pulp and repeat until you've squeezed out all the ginger juice. You should now have 4 cups of liquid. If you don't have 4 cups, the ginger you used may have not been fresh, but just add water to make 4 cups.
- Add the ginger juice to a large pot along with 6 cups of sugar. Heat the mixture over medium heat to a full simmer. It has a tendency to boil over, so keep a constant eye on it and lower the temperature if it looks like it's going to boil over. The impurities that made the juice cloudy will float to the top as foam, so use a fine mesh skimmer or spoon to remove the foam from the syrup and discard. After the foam stops forming and the syrup is clear, your ginger syrup is done.
- You can pour the hot syrup into sterilized glass bottles, or let it cool and transfer it to a suitable container. Stored in the fridge it will last for 6 months.
