Whisk lemon/lime juice, honey and gelatin in a sauce pan until there are no lumps.
Heat over low heat until it’s nice and melty, stirring constantly.
Add food coloring if desired – you’re almost done now!
Grab an ice cube tray or silicone mold (I don’t recommend silicone usually but since we’re not baking with it here I think it’s fine). You can use a basic pan, too, and then just cut into squares or use a cookie cutter after it’s set.
Pour in the mixture, then pop in the freezer for 5-10 minutes to firm up. Once they’re out of the freezer they will stay firm at room temperature.
