This is from a collection of recipes from books I own, but which I haven't myself tried yet. However, you can have faith that at least the authors themselves have tried them, so they're not deadly or anything.
Grand Orange-Cognac Liqueur
Place zest and sugar in a small bowl. Mash together with the back of a wooden spoon or pestle. Continue until sugar is absorbed into zest. Place in aging container. Add cognac. Stir, cap and age in a cool, dark place 2 to 3 months. Shake monthly.
After initial aging, strain and filter. Stir with a wooden spoon to combine. Cap and age 3 months more before serving.
 Seville oranges produce the authentic taste but any type of orange peel/zest may be used with good results.
