Start with a good chocolate. You can use semisweet chocolate chips but a good quality milk chocolate from your local cake and candy shop is good. You can go upscale with fancy Swiss or Belgium versions but it isn’t necessary. Melt the chocolate over hot water or VERY Carefully in your microwave. Melt a bit. Stir a lot. Once the chocolate is smooth add a small amount of Grand Marnier or other orange flavored liqueurs. (Perhaps a tablespoon to a cup of melted chocolate.) Stir. Add in a few tablespoons of heavy cream. Stir. You may need to warm it a bit more. You may need to add more cream. If it separates out just keep stirring and adding more warm cream. It will come together eventually. Put in a fondue pot and keep warm. Serve with marshmallows, pineapple, pound cake, angel food cake, apples, and fingers… (Oops not fingers!)
For a large crowd I provide wooden skewers instead of the 3 remaining fancy forks that came with my fondue pot. That way there isn’t any confusion about which belongs to who and everyone can enjoy the chocolate.
If you don’t have good temperature regulation on your fondue pot, i.e. a candle or sterno pot, you will need to keep track of this heat it when it gets cool and blow it out the rest of the time as the candle can scorch the bottom.
