In all the hubbub of traveling this week I forgot to post this short tutorial. This sauce (really a syrup) is simplicity itself. Assemble your ingredients, then combine the sugar and cocoa powder.
Add the water.
Set it on to simmer. Boil it for 3-4 minutes, then let it cool for about five minutes. Add the chocolate and vanilla and stir until the chocolate is completely melted.
Allow it to cool another twenty minutes or so, then pour it into the container of your choice. A squeeze bottle works quite well!
Store this for up to a month in the refrigerator.
