This should be done ahead of time since the pan needs to be set and cool for at least 20 to 30 minutes before adding the mixture. 1. * Add 1/2 cup of the sugar to the pan. Melt the sugar over medium heat until it caramelizes. Be careful not to burn the sugar. Keep shaking the pan so that all the sugar melts. 2. * Once the sugar has melted and is a light brown, turn the pan so the liquid coats the sides, about 2-1/2 to 3 inches up from the bottom. Set aside the pan and let cool.
