Here's my personal recipe for Soufflé Glacé au Grand Marnier
Very easy to make, BTW. It's usually the dessert on Xmas Eve dinner.
50 gr butter (room temperature)
4 egg yolks
5 table spoons icing sugar
5 table spoons Grand Marnier (or Cointreau)
200 ml cream
4 egg whites
Take the largest bowl. Put butter, egg yolks and icing sugar. Mix until it's a creamy mass.
Incorporate Grand Marnier.
Beat well the cream in a smaller bowl and incorporate into the mass.
Finally, incorporate (without beating!) the well beaten egg whites.
Put into a recipient or small soufflé forms and let freeze for several hours.
To serve and depending on the way you froze the mass, either use an ice-cream portioner and make scoops or overthrow the 'cake' onto a serving plate and put dark non-sugared chocolate powder over it.
Makes about 6-8 servings. You can serve some peeled orange filets with it.
