I found this on a website, and have been using it for several years for Passover. It has always been a big hit with the family. You can make this year round as well.
- Melt the chocolate with the butter, water and the coffee granules. Cool slightly.
- In a bowl, beat the egg yolks. Beat in 1 tablespoon sugar. Add to the chocolate mixture and mix well.
- In an other bowl beat egg whites until stiff peaks form. Add one tablespoon sugar and continue beating until soft peaks form. Gently add to the chocolate mixture until well combined.
- Refrigerate until ready to serve.
