I've made, eaten and served plenty of hot fudge. I have not had much experience with white hot fudge. Since I hadn't experienced it, I figured I should create my own. I started with hard crack sugar syrup. I added cream to dissolve the sugar mass. I stirred white chocolate and salt into the cream-sugar mixture. The finished hot fudge resembled the traditional dark chocolate version in chew and pourability. The flavor is sweet, vanilla and rich fattiness, molten white chocolate. Time to start topping some frozen custard.
