First off, if you care about how clear your ice is, the best thing to do is start with distilled water that you’ve boiled twice. In our test recipe, we used tap water boiled once and found that worked, too.
You can spritz your clean dry mold with cooking spray to ease removal at the end of the process.
To serve, hold mold upside down under hot running water until ice lick loosens.
Serve to your dog somewhere you don’t mind getting wet and a little messy!
Take lots of photos and videos.
