12 oz. bag semi-sweet chocolate chips
1 quart heavy cream
1/4 cup sugar
1/4 cup Grand Marnier or your favorite liquor
Melt chocolate chips over a double boiler, or use a bowl over simmerming water. While the chocolate is melting whip 1 cup of the heavy cream to soft peaks. Cream that is whipped too stiff will produce a grainy mousse. Use a whisk to make sure all the chips have melted. Remove from heat.
Whisk 1 cup of liquid heavy cream into the melted chocolate. Add approx. 1/4 cup of your favorite liquor and whisk to incorporate. Fold in your whipped cream until incorporated and then viola! – chocolate mousse! Of course you can leave out the liquor. The mousse will not change much in texture, but do increase the sugar in your whipped cream to 1/2 cup.
