Preserving in Alcohol

Distilled spirits like rum, brandy, eau de vie or vodka, which are at least 80 proof (containing 40 percent alcohol) may be used for flavor. Pure ethyl alcohol, generally sold in strengths up to 95 proof, is a cheaper alternative. As high proof alcohol tends to shrink the fruit and some sweetening is desirable, it is generally mixed with a sugar-and-water syrup before use. For each 1 lb/500 g fruit, you will need 2 cups/500 ml alcohol and a syrup made with ½ cup/100 g sugar and ¼ cup/60 ml water.
