Phosphate Soda

Ingredients

• 2 tbsp Chocolate Syrup (Or any other flavored syrup like cherry or vanilla)
• 0.5 tsp Acid Phosphate (This is the key ingredient for the authentic tangy flavor)
• 300 ml Seltzer Water (Must be very cold for best results)
• 4 cubes Ice Cubes (For chilling)

Instructions

1. 1

   In a tall, chilled glass (like a Collins or fountain glass), add the chocolate syrup and acid phosphate.

2. 2

   Pour in a small amount of the cold seltzer water, about 60 ml (1/4 cup), to cover the syrup.

3. 3

   Using a long spoon, stir vigorously for about 20-30 seconds until the syrup and acid phosphate are completely dissolved into the seltzer. This creates a smooth, uniform base.

4. 4

   Add the ice cubes to the glass.
