Ginger Lemongrass Drink

Xả gừng literally translates to lemongrass and ginger. I love lemongrass, and the flavor it imparts to the drink is very pleasant and refreshing on a hot day.
Lemongrass (xả) is very common in Vietnamese cuisine. It is considered a mild diuretic, tonic and stimulant. Lemongrass is typically sold in packs of 5 stalks, and can be quite expensive. Last year, I asked Lulu whether we could grow it at home, and in response he planted 4 "bushes". They are doing quite well, and since it is a perennial, we keep getting fresh stalks. If you're planning on cooking a lot of Asian cuisine, consider investing in some lemongrass.
Ingredients
Yields: 6
2-1/2 cups superfine sugar, to taste5 cups water
1/4 cup palm sugar
1 quart ice cubes
4 stalks lemongrass, + extra for garnish
2 chunks ginger, about 3 inches
1/4 cup crystallized candied ginger, cut in half
Directions
For the lemongrass: Wash the lemongrass. Remove all the white powder from the leaves and also a few outer leaves. Cut the stalks in half and crush them with the back of a chef's knife. Cut the remaining stalk into extremely thin slices using a chef's knife. In a mortar and pestle, grind the thin slices of lemongrass, then transfer and mix everything using a mini food processor. It should turn into a fine moist powder. Set aside.
For the ginger: Clean the ginger, carefully removing any dirt. You don't have to peel it. Thinly slice both chunks. Set aside.
For the lemongrass water: Combine the water and lemongrass powder. Bring to a boil and let simmer for about 15 minutes. Filter through a fine sieve.
For the caramel syrup: In a sauce pan, melt the sugar without any water over high heat. It's important to carefully watch the sugar; as soon as the edges of the pan start caramelizing, immediately lower the heat to medium-low. Gently jiggle the saucepan in circles. Do not use a spoon! Lower the heat to the lowest setting when there are only a few remaining non-caramelized pieces. Don't let the sugar get dark brown or you'll get a burnt taste.
Assembly time: When all the sugar is an amber color, remove from the heat, pause for about a minute (be careful of splattering when the water is added), then slowly add the boiling lemongrass water, palm sugar, fresh ginger and candied ginger. Stir constantly with a wooden spoon. Bring back to a full boil then let simmer for about 10 minutes. Remove from the stove and cool completely.
Serve in tall glasses with ice; stir well and garnish with a stalk of lemongrass.
Enjoy with tea cakes or cookies.
Time to relax!
Tips
You can find lemongrass and palm sugar in most Asian stores. If you don't have any, you can always replace them with lime juice and regular sugar.

I like making the caramel first to give a nice amber color to the drink. If you don't mind a lighter color, just make a simple syrup by dissolving the sugar in about 2 cups of water; bring to a boil and simmer for about 2 minutes.
I prefer using superfine sugar. It's a fine-grained sugar and it dissolves much more quickly than the regular one.
You can strain the liquid right before serving if you want the lemongrass to infuse for a long time.
