Covers an 8" cake (see Christmas Cake recipe)
Ingredients:
- 3 medium egg whites
- 500g-600g icing sugar (approx)
- 1 tbsp lemon juice
- ½ tsp glycerine
Method:
- Stir sifted icing sugar gradually into egg whites and lemon juice until icing falls thickly from spoon. Note: may NOT need all 600g icing sugar.
- Whisk for 10 mins until icing stands in stiff peaks. Stir in glycerine.
- Spread over cake, making soft peaks.
- Set for 24 hrs before boxing up.
Tip: To prevent royal icing from setting too firm add ½ tsp glycerine per 500g icing, after the icing forms stiff peaks.
