You should cook it for 5 to 10 minutes. If the mixture starts to stick to the bottom, lower the heat.
To test if the fudge is ready, simply tilt the pan and if the mixture comes off from the bottom of the pan, you’re good to go. Mixture will look shiny and firm. If you run a spatula on the bottom of the pan, fudge will take a few seconds to come together again. You are looking for a very thick stage.
Cooking time: cooking time will vary a lot depending on the brands of condensed milk and caramel candy you use. Please read the recipe above to see what you are looking for in the consistency.
To roll: You can roll the fudge in anything that comes to mind, sprinkles, sugar, shredded coconut, finely chopped nuts.
