Some recommend to turn the sucrose syrup into an invert sugar syrup by adding an acid such as citric, tartaric or cream of tartar (potassium hydrogen tartrate). For 2 lbs of sugar (1 kg.), 1 pint of water (500 ml.), add 1/4 tsp. (1 g.) acid (or juice of 1/2 lemon). Bring to boil and simmer for 15 minutes. Cool. The sucrose is split into glucose and fructose. It is said that invert sugar syrup gives a softer taste.
The addition of sugar should not affect the essential oils. Often 1 tsp. of glycerine is added to 1 litre of liqueur to make it thicker and smoother.
The basic recipe for a fruit liqueur is -
Sugar syrup is 1 part water to 2 parts sugar. 1/2 cup water + 1 cup sugar yields 1 cup syrup.
1 cup syrup + 3 cups alcohol (40%bv) = 30%bv liqueur
2 cups syrup + 3 cups alcohol (40%bv) = 24%bv liqueur
If using 95%bv alcohol, use twice as much syrup, with an extra 1/4 cup of water per cup of syrup.
