STEP 1/7
Wash 200g of blueberries in cold water with 2 tablespoons of vinegar, rinse them three or four times, and drain them. If you add half a cup of sugar and half a cup of water and shake the pot slightly, the sugar melts to some extent. Metering is based on paper cups.
STEP 2/7
When it starts to boil over medium heat, reduce the heat and boil it for about 15 minutes, then add 1 tablespoon of lemon juice to complete it.
STEP 7/7
Sprinkle a bit of chocolate syrup and condensed milk, and it's done. Mix milk about 2 tablespoons before drinking. Otherwise, the ice melts too quickly because of milk.
