Chocolate syrup

INGREDIENTS:

1 cup good quality unsweetened cocoa powder1 cup granulated sugar1 cup cold water1/2 teaspoon kosher salt (or to taste)1 tablespoon vanilla extract

DIRECTIONS:

In a medium saucepan, whisk together the cocoa powder and sugar until blended. Add the water and 1/4 teaspoon of the salt, and whisk over medium heat until boiling, stirring constantly.Continue boiling until mixture thickens, about 3 - 4 minutes. The mixture will still be fairly thin (it thickens to a syrup-like consistency once cool). Taste and stir in additional salt until dissolved, up to 1/4 teaspoon, if desired.Remove from heat and stir in the vanilla. Cool.Store syrup in an airtight glass container in the refrigerator. The syrup should keep, refrigerated, for at least a month.
