What to make with egg whites.

I had a couple of egg whites in the fridge from a sauce  that only used the yolks.

So I beat  them up ,intending to make some meringues. Unfortunately there must have been some egg yolk in there  ,as they simply refused to firm up, by which tine I had already added some caster sugar.

I am loath to throw anything away......so ,what to do with them? 

Added about 150 Grammes of dark chocolate which I had melted in the microwave,and then beat in just under half a pint of double cream. 

The result is velvety and not too strong. It shouldn't need further attention,except to eat it! 

When it has  firmed up I shall take a photo of it.

Just the right thing to eat when the rain is pouring down.
