Mirror glazes eye catching, versatile and easy to make.  The standard recipe requires gelatine, which is an animal based product.  Thankfully, there’s also a plant based alternative to gelatine that works just as great and that’s agar agar.  Today I will create this galaxy mirror glaze using agar.

Let’s jump to the ingredients.  

Galaxy Mirror Glaze Ingredients:

  • 170g sugar
  • 200g white chocolate (couverture works best)
  • 11g Agar
  • 145g water
  • 115g sweet condensed milk

Tips to working with agar:

There’s three aspects you need to be aware of to use agar successfully. 

  1. Agar needs to dissolve in liquid
  2. It needs to cook for a minute or two to get activated
  3. It sets at room temperature.  

Instructions for Mirror Glaze using agar:

  1. From the 145 ml water, pour 4 - 5 table spoons over the agar and let it sit for a few minutes.
  2. In a pot add sugar, sweet condensed milk and remaining water.  Place over medium heat while continously stirring.  The goal is for the sugar to fully dissolve.  Rub the mixture between your fingers to ensure no sugar remains.
  3. Pour the agar the agar into this mixture.  To active the agar, it needs to cook.  Place the pot on high heat and stir occasionally.  As soon as it starts to bubble, remove from the heat and continue stirring for a few seconds.
  4. Pour in the white chocolate and let is sit for 30 seconds until the white chocolate has melted.
  5. Blend this mixture to ensure no lumps.
  6. Sift the mirror glaze into 4 different bowls.
  7. Color the mirror glazes into: purple, navy blue, pink and white.  
  8. Pour the mirror glaze over a smooth cake and brush the glaze to create a galaxy look.
  9. Press a tooth brush into white gel based food color and sprinkle some stars onto the galaxy.
