We simply start with 1/2 bottle (liter size) of vodka or brandy. Add 1 cup sugar and shake until it all dissolves. Then, fill the remaining space with blackberries or chokecherries or raspberries or dried apricots or diced fresh peaches. Keep in a cool dark place for a month. Enjoy. We have some homemade liqueurs that are over 5 years old and are still as good as when made. When the liqueur is gone, use the fruit on ice cream or pancakes.
