chocolate coffee fudge

Found this on the Cooking with Trader Joe's recipe blog.  YUMMMM....

1 14-oz can Organic Sweetened Condensed Milk
2 Tbsp instant coffee (or espresso powder)
1/2 Tbsp water
1 12-oz bag semi-sweet chocolate chips

1.) Heat the condensed milk in a heavy saucepan over medium heat.  
2.) Dissolve the instant coffee in the water (it will be thick) and stir into the condensed milk. (You can also just toss the instant coffee into the condensed milk but it won't dissolve completely. I tried this the first time and actually liked the effect of tiny bursts of coffee flavor throughout the fudge).
3.) Add the chocolate chips, lower the heat, and stir until melted and smooth (don't scorch it!).
4.) Pour into an oiled 8x8-inch pan.  Chill in fridge until set (about 2 hours).
