Sift the cocoa powder. This is important to ensure the syrup is smooth.
Add the sifted cocoa powder, organic cane sugar, milk, and a pinch of salt to a pan over medium heat.
Whisk continuously for about 3-4 minutes or until the sugar is melted. This syrup will continue to thicken as it cools. If you want a thinner consistency, add 1-2 more tablespoons of milk or water.
