6 frozen Pandan leaves (can find at any Asian supermarkets)
1 dry Luo Han Guo (can find at any Chinese herbal stores)
3 litres of water
Pour water to a big pot at high heat.
Break Luo Han Guo open, take out fruit and divide into small parts before putting in the cooking pot.
Add Artichokes and Pandan leaves into the pot as well. Cover lid until water gets boiled, and then lower the heat to medium.
Continue cook at medium heat for 10-15 minutes before turn off the heat.
Let the liquid cool completely. Remove artichokes, panda leaves and Luo Han Guo fruit with a slotted spoon.
Add sugar or syrup at your preferred sweetness (I usually add 3 tablespoons of organic granulated sugar)
Pour the drink into drink containers and store in a fridge to keep cool.
