Some people might consider it overkill to mix caramelized sugar with the lush flavor of butterscotch. But since the beauty of being an adult is that we can do pretty much as we please, I don’t feel the need to apologize for mixing the two in one cool custard. If you want to ramp up the flavor of the butterscotch custard with even more flavorful molasses notes than dark brown sugar can supply, try using one of the unrefined brown or cane sugars that can be found in natural food stores. Look for ones that are dark and ruddy, since they tend to have the most flavor.
