In a microwaveable bowl, place heavy whipping cream.
Microwave it for about 45 seconds bringing it to the beginning of a boil, but not boiling.
Remove from the microwave.
Add in 1/2 C of the meltable chocolate pieces. (chocolate chip morsels work quite well)
Allow it to sit for a few minutes then stir.
Add in the rest of the chocolate pieces.
Again let it all sit for 2 minutes or so.
Now stir, not rapidly but to combine.
As you stir, it will thicken.
If it is not getting thick enough add more chocolate pieces.
*Tip >>Heavy whipping cream thins, while the chocolate thickens.
Stir and the color will change.
Add a drop of your chocolate coloring for candy in. (if you are happy with the color of your melting chips, you don't need this step, but if you started with white chips, you have to color them red)
Stir.
If the color you want is not there yet, add another drop or 2 until you achieve your blood red.
