1/3 cup orange zest*
1/2 cup granulated sugar
2 cup cognac or French brandy
1/2 teaspoon glycerin
Place zest and sugar in a small bowl. Mash and mix together with the back of a wooden spoon or a pestle. Continue mashing until sugar is absorbed into the orange zest and is no longer distinct. Place into aging container. Add cognac. Stir, cap and let age in a cool dark place 2 to 3 months, shaking monthly.
After initial aging, pour through fine mesh strainer placed over medium bowl. Rinse out aging container. Pour glycerine into aging container and place cloth bag inside strainer. Pour liqueur through cloth bag. Stir with a wooden spoon to combine. Cap and age 3 more months before serving.
NOTE:
Grand Marnier is a classic orange liqueur to be savored. While ordinary brandy can be used, we recommend a good cognac or French brandy for best flavor. Ready in 5 to 6 months. Makes about 1 pint.
* Authentic Grand Marnier uses bitter Haitian oranges to produce its classic taste. You may use any type of orange peel you wish; however, a bitter type, such as Seville, is preferred for authenticity.
