bittersweet chocolate sauce

1 1/2 cups bittersweet chocolate--chopped
(please use good chocolate...with a 57% or more cocoa content)
3/4 cup heavy cream
1/4 cup + 2 Tbs granulated sugar
2 Tbs water or other liquid (you can use coffee or liqueur or poaching liquid)
3 Tbs corn syrup (if you are opposed to corn syrup or don't have it...omit it..it is not essential..it won't affect the taste)

Place all ingredients together in a double boiler after the water has begun to boil  Don't let the mixture get too hot, it should just be warm enough to melt the chocolate and sugar.  I like to turn the heat off the pot once the water begins to boil, it will have enough residual heat to do the job.  Once chocolate is melted stir so the ingredients all mix nicely together and you are ready to serve.  This will keep for a couple of weeks in the fridge.
