The royal icing recipe I have uses 1 egg white with 200g powder sugar.
I use egg white powder to substitute the raw egg white, the instruction on the packaging is 1tsp of egg white powder + 7tsp of water equal to 1 egg white.
I am confused because recently I am using Wilton meringue powder, on the back of the packaging, it stated 2tsp of meringue powder + 2tbsp of water = 1 egg white,
But there is a little recipe come with it said royal icing recipe need 3tbsp meringue powder + 6 tbsp water with 500g powder sugar
Why is that? for me there will be a lot of egg white
