Colored Mirror icing for cake

1. Soak the gelatin. If the gelatin is loose, then 12 g of gelatin should be filled with 60 ml of cold water (room temperature), stir and leave to swell. If the gelatin is leafy, then 100 ml of water is needed for 12 leaves of gelatin.
2. Put glucose syrup in a saucepan (it should be thick), pour water and add sugar. Put a saucepan on the stove, bring to a boil and cook at a high boil for 2 minutes. Or, if you have a thermometer, the final temperature of the syrup should be equal to 105 degrees.
3. Put the chocolate broken into pieces in the hot syrup and mix well until smooth. Add condensed milk and mix again.
4. When the mass is not boiling and has cooled slightly (up to 60 degrees), add gelatin to the glaze. If you have powdered gelatin, add it as it is, with water (otherwise it will not work), and if it is leafy, squeeze it out of the water and add it to the glaze.
5. Pour part of the glaze through a sieve. It will be streaked on the main surface. Add a small part of the white dye and mix. Tighten it with a film in contact with the surface. Color most of the glaze as you like. If you need a pure color, also first paint it white.
6. The working temperature of the glaze is 35 degrees. Bring it to this temperature and cover the cold cake with most of the icing. Immediately pour the white glaze in a thin stream, creating approximately the shape you need (circles, lines, spirals, etc.) After 10 minutes, when the glaze stops flowing, and the final pattern on the cake will appear.
Have a nice and beautiful cakes for you!
PS You can experiment with this technique - paint the glaze with different colors and try their combinations, apply the glaze with spots, after applying all the layers of glaze, go through it with a spatula...
