Pour 80g of water into a bowl and sprinkle over gelatin and leave to bloom, about 5 minutes.
Place the bloomed gelatin in a bowl with the white chocolate.
Combine: corn syrup, sugar, water and condensed milk in a saucepan and heat over medium till the sugar dissolves completely.
Pour the syrup mixture over the white chocolate mixing till the chocolate has melted, use a blender or an immersion blender to make completely smooth.
Add white food colouring to adjust the colour of glaze.
Separate some of the glaze and tint to desired colour(s)
The glaze is ready to use when it has cooled to about 35 – 40˚C (95 – 104˚F) – use an instant read thermometer to check this.
