I called these ice cubes because I made them in a flexible silicone ice cube tray which I bought at Casa and I'm sure you can find them just about everywhere these days. You can also use a flexible mini-muffin tin or paper muffin cups but I think the small size of the ice cube tray is perfect. This makes 32 "ice cubes" - they will be gobbled up quickly but can be stored in the freezer for a couple months
