Boil the water before freezing it. Let it cool to near room
temperature in the pot you boil it in and then pour it into the ice
tray (try do do this without disturbing/stirring up the water any
more than necessary) and put it in the freezer.
This will work but dissolved gases often cause clear liquids to turn opaque white when frozen. You should boil the water for at least 5 minutes to get rid of most of the dissolved gases.

Dissolved gase / air make the ice clear or opaque....

All ice is as clear as the water it is made from. Entrapped air, particulate matter, or dissolved solids will affect the clarity of the water and, thus, the ice. Ice often appears white when there are abrasions or frozen condensation with entrapped air on the exterior of the ice.

Ice appears clear when there are no air bubbles trapped inside, and when its surface is smooth (not scratched).
