Chocolate Sauce

Place in a pot and mix well:

½ C water
¼ C cocoa powder (I use Van Houten)
1 C sugar 

Gently boil for 3 minutes, stirring occasionally so it doesn't burn. Then add: 

a pinch of salt
50 gm dark chocolate (I use 1 bar of Ghana Black)

Wait for about a minute for the chocolate to melt, then stir gently. When cool, add:

¼ t vanilla extract

Store in an airtight jar in the fridge. This lasts a long time.
