Icing for Armenian Nutmeg cake

Hey Guys, I'm sorry I haven't posted for a while but I've got some crackers lined up that I keep meaning to put up. First up; Icing for our cake. Now this is not at all neccessary, the cake is fantastic just the way it is. However, this is good icing. You will need;
100 g cream cheese
500g icing sugar
1 lime
a good two inch piece of fresh ginger
First, if you have a juicer, peel both the lime and the ginger and juice. If you do not have a juicer, squeeze the lime juice into a cup, then peel the ginger and grate very finely. I have not tried this way yet but reckon it should be pretty good too.
Next, put the cream cheese in a mixing bowl and begin to cream in the icing sugar, a little at a time. When it starts to become quite firm, add the lime and ginger juice, stirring all the time. Keep adding the sugar, making sure to taste as you go along. When you have great tasting icing with a fairly firm texture, ice the cake. Easy. This amount of mixture is a bit too much for one cake, but you've got to have some left over to eat with a spoon now don't you?!!
