In a small bowl, mix together the cocoa powder and salt; set aside.

In a 3- or 4-quart pot, mix together the water and sugar.

Turn heat to medium and heat to boiling, whisking constantly.

Once the sugar water is boiling, add the remainder of the ingredients, whisking constantly.

Note that when the cocoa powder is added, the mixture will bubble up in the pot.

Lower the heat and continue to whisk and cook the sauce for about 15 minutes; the liquid will be reduced and the sauce will thicken slightly.

Cool and use it over ice cream, fruit, cake, or mixed with milk for chocolate milk or hot chocolate.

You can also water-bath can the chocolate sauce.

Use half-pint or 4-ounce canning jars and process for 15 minutes.
