Weigh all the ingredients.
Put raw cane sugar, Fleur de Sel and 3 spoons of the cocoa into a spice grinder and blitz it for 30 secs.
It is done when it looks like brown powdered sugar, if it doesn't look like this, then give it another 30 secs.
Put all ingredients and your brown powdered sugar in the mini food processor and pulse until the chocolate is completely powdered.
Avoid running the food processor for a long time as it heats up the motor and a hot motor will melt the chocolate, so it is best just to use pulse.
Put the instant chocolate powder into a jar or a few smaller jars, if you are making gifts.
Use 1-2 tablespoons per cup of hot chocolate depending on the size of the cup and desired intensity. Make sure the milk is around 158-167 Fahrenheit when you stir the powder into the milk.
