Step 1: Melt the Chocolate

1. Break the chocolate into small pieces and place it in a heatproof bowl.
2. Melt the chocolate using the double boiler method: set the bowl over a pot of simmering water (ensure the bowl doesn’t touch the water). Stir until smooth.
3. Keep the chocolate at a temperature of 30–32°C (86–90°F). If you don’t have a thermometer, test it with your fingertip—it should feel slightly warm but not hot.

Step 2: Prepare the Molds

1. Using a silicone mold for candies, brush a thin layer of melted chocolate onto the bottom and sides of each cavity.
2. Place the mold in the freezer for 5 minutes to set.

Step 3: Make the Filling

1. In a mixing bowl, combine caramelized condensed milk, sweetened condensed milk, chopped walnuts, and a pinch of salt.
2. Mix until smooth and evenly combined.

Step 4: Assemble the Candies

1. Remove the mold from the freezer and fill each cavity with about one teaspoon of the prepared filling.
2. Pour more melted chocolate over the filling to seal each candy.
3. Smooth out the tops with a knife or spatula.

Step 5: Chill and Decorate

1. Place the filled mold back in the freezer for another 5 minutes or until fully set.
2. Carefully remove each candy from the mold.
3. Optional: Decorate with edible gold paint or other toppings as desired.
