Royal icing

• egg whites↗3
• icing sugar↗600g g
• liquid glucose↗1 tsp tsp
• lemon juice↗1 tsp tsp

Step-by-step instructions

1. 1

   Whisk the egg whites until lightly whipped. Add the icing sugar a few tbsps at a time, whisking continuously until all incorporated. Add the glucose and lemon juice.

2. 2

   Continue whisking until the icing is thick enough to hold stiff peaks when you lift the beaters and is smooth and shiny.

3. 3

   Use a palette knife to spread the icing over the top and sides of your marzipaned cake. For a snowy effect, make little dips and peaks with a teaspoon. Leave to firm up somewhere cool and dry (not the fridge) for 24 hrs before cutting the cake.
