Making royal icing without using raw egg white?

[Chottie]

Please can you advise? I usually make royal icing to ice my Christmas cake. It is made with raw egg whites, now DD is expecting, I was thinking about using powdered egg whites instead. Has anyone tried this? did it work?

Can you use the royal icing powder? It's dried pasteurised egg I think. In a greeny blue and white instead on pink and white box IIRC. Just add water.

Thanks jennimoo I have found a pack in the cupboard that DH used to make macaroons, so I have checked the ingredients, it is pasteurised powdered egg whites, so I will use them.
