Step 1: Making Condensed Milk

1. 1. Prepare the Milk: Pour 600ml of milk into a heavy-bottomed pan. Turn on the heat to medium.

1. 1. Add Sugar: Incorporate 160-170g of sugar into the milk, adjusting the quantity based on how sweet you want your chocolate. Stir continuously until the sugar dissolves completely.
   2. Heat Adjustment: Keep the heat on medium-low and let the mixture gradually come to a boil. Frequent stirring is crucial to prevent the milk from sticking to the bottom of the pan.
   3. Watch the Boil: Once the edges start to boil, reduce the heat to low to avoid overflowing. Continue to stir and cook until the milk mixture thickens and turns a pale yellow color.

1. Finish Condensed Milk: Turn off the heat once you achieve a thick consistency. Congratulations, you’ve just made homemade condensed milk!

Step 2: Mixing Cocoa Powder

1. 1. First Addition of Cocoa: Lay a sieve over your mixing bowl and sift 100g of cocoa powder into the condensed milk. This ensures your chocolate is smooth and clump-free.
   2. Mix Well: Stir the mixture vigorously until the cocoa is fully incorporated and begins to darken and thicken.

1. Second Addition of Cocoa: Add the remaining 30g of cocoa powder. Mixing might be tough due to the dryness, but persist until it’s well combined.

Step 3: Setting the Chocolate

1. 1. Prepare for Freezing: Transfer the chocolate mixture onto a cling wrap-lined baking tray. Tap gently to flatten and even out the surface.
   2. Freeze: Cover with another piece of cling wrap and freeze for about 40 minutes, or until the chocolate is firm.

1. Cocoa Dusting: Before cutting, dust the chocolate with a thin layer of cocoa powder for an extra touch of chocolatey goodness.

Step 4: Serving

1. Cut into Pieces: Remove the chocolate from the freezer and cut into bite-sized pieces. This is where you can get creative with shapes!
2. Presentation: Arrange your chocolates neatly. They’re not only delicious but also visually appealing, perfect for gifting or enjoying during a family gathering.
