Wintermelon Milk Tea

0 Peel and dice the wintermelon and place into a bowl. Sprinkle with brown sugar, mix well, and allow to sit for 1 hour.
1 Pour the wintermelon and all juices into a pot and bring to a boil.
2 Sprinkle with rock sugar or coconut sugar, reduce heat and simmer for 20-30 minutes while stirring every 5 minutes to prevent the wintermelon from burning. Once cooked the wintermelon will be translucent and the juices will have thickened.
3 Remove from the heat and place the wintermelon and juices into a highspeed food processor and blitz until smooth.
4 Strain the wintermelon pureé, set aside and allow it to cool.
5 Meanwhile simmer 2 cups of water, remove from the heat and add the tea bags, steep for 5 minutes. Remove the tea bags and allow the tea to come to room temperature.
6 While the tea is cooling bring a small pot of water to a boil, add the tapioca pearls, reduce heat and simmer for 5-6 minutes.
7 Strain the pearls, add to a small bowl, and stir through the brown sugar. Set aside and allow to cool.
8 To assemble the drink: Evenly divide the soaked tapioca pearls and syrup between four glasses. 
9 Divide the ice between the glasses, top with the wintermelon syrup, tea, and milk.
