The secret to creating Halloween food is having the right tools, and by tools I mean… cookie cutters, pans and molds! Skull molds are the easiest way to Halloween-ify anything, they are a must have in the Halloween food game. I have tons of them in all different sizes and materials from metal, to plastic, to silicone. So, I was super excited when Shaped Ice Molds (affiliate link) gave me their new extra large skull and sphere ice mold to try out. I used them both to make this extra ‘COOL’ Grim and Tonic!  It’s easy to make because the mold does all the Halloween heavy lifting all on it’s own, so I decided to not just to make regular ice, I added blue butterfly pea powder to water to make these sky blue skulls. Then, staying with the blue theme, I used Empress 1908 gin that is a gorgeous indigo color and when splashed with tonic turns a beautiful violet…it’s just stunning and so magical. I added a few chips of dry ice for effect and voila!…Grim and Tonics for everyone! Happy Halloween!

Servings: 4



  • 2 cups water (This will make 4 blue skulls)
  • pinch blue butterfly pea powder (add more if a darker blue is desired)
  • 2 cups water (This will make 4 sphere molds)
  • 4 oz Empress 1908 gin
  • tonic water
  • lime curls and lavender sprigs (garnish)


  • Make ahead: Add butterfly pea powder to 2 cups of water in a small saucepan and heat until dissolved. Allow to cool and then filter blue water through a coffee filter, changing out the filter as needed. Pour blue water into skull mold and freeze overnight.
    Add plain water to the sphere mold and freeze.
    Repeat until you have 4 skulls and 4 spheres.
  • Add the round ice cube to the bottom of the glass and then add 1-1½ oz. of Empress 1908 gin. Add lime garnish and tonic water . The tonic will turn the blue gin, purple. (Sooo pretty!!) Now add the blue skull ice cube and top with more tonic if desired. garnish with lavender and dry ice for effect. (Warning: Use caution when handling dry ice and take care not to ingest dry ice, it is not edible and will burn)

    I have the slightly smaller size of these Shaped molds, so I bought some butterfly pea powder to try out your recipe. Wow the color!! The blue and the change to purple are beautiful.
