First ensure that your utensils and cutlery are dry before melting the chocolate
Wet cutlery and utensils will cause the melted chocolate to seize (harden) and become unusable
The chocolate for the topping can either be melted in the microwave or on the stovetop:
If you are melting the chocolate in the microwave: Melt the chocolate pieces in a dry bowl in the microwave. Check on it every minute, stirring with a dry spoon. Depending on the wattage of your microwave, it may take between 2 to 4 minutes for the chocolate to melt completely.
If you are melting the chocolate on the stovetop: Place the chocolate in a heat-resistant bowl, ensuring it fits snugly over a pot of simmering water. Make sure the water doesn't come into contact with the bottom of the bowl. Stir occasionally until the chocolate melts. Once melted, whisk the mixture until it becomes smooth and glossy.
Optional: You can add a tablespoon of coconut oil while melting the chocolate, you'll achieve a super smooth consistency that's just perfect for dipping.
If you're using powdered or gel tint/color, simply mix it into the melted chocolate.
Remember to avoid adding any liquid, like water based flavoring extracts or coloring to your melted chocolate. This will have the same effect on the chocolate as adding water or moisture.
Try to find a cup for the melted chocolate that is not too wide. This way, you can dip the cookie sticks easily without needing a lot of chocolate. A shot glass or tall narrow cup works perfectly.
Dip each cookie in the melted chocolate and set on parchment paper to dry.
