Preheat oven to 325 F.
Combine cream and salt in a saucepan over low heat until just hot.
Remove from heat.
Put yolks and cotton candy in a heatproof bowl.
Pour about 1/3 of the hot mixture into the cotton candy bowl and stir until most of the cotton candy has dissolved.
Pour the combined mixture back into the saucepan with the rest of the hot mixture. Stir to combine.
Place 4 ramekins in a baking dish, and pour mixture evenly between the four ramekins.
Fill the baking dish with boiling water to halfway up the sides of the ramekins.
Bake for about 40 minutes, till the centers of the crème brulees are barely set.
Remove from oven and take ramekins out of the baking dish. Cool for at least 15 minutes before refrigerating for several hours.
Top with sugar, and torch till sugar is melted. Sugar will harden. Decorate with additional cotton candy!
