- Choose chocolate specifically made for melting.
- Avoid chocolate chips containing wax or stabilizers.
Layering Technique
- Wait until each layer is properly set before adding the next.

- Keep offset spatula clean between layers.
Cutting Perfect Squares
- Use a ruler to mark cutting lines.
- Heat knife under hot water before each cut.

Troubleshooting Common Issues
- If layers separate: Ensure each layer is at the right temperature before adding the next.
