For a pretty pink, add one drop of red food coloring.
In the bowl of an electric mixer fitted with the whisk attachment, beat egg white until stiff but not dry, about 2 minutes. Add the sugar and the lemon juice; beat 1 minute more. If the icing is too thick, add a couple drops of water; if icing is too thin, continue beating to achieve desired consistency.
Raw eggs should not be used in food for pregnant women, babies, young children, the elderly, or anyone whose health is at all compromised.
