Last year we did this:
Pear Drop and Sarsaparilla Vodka!
Simply pour vodka over some sweets - Pear Drops and Sarsaparilla work most excellently :) Something like Kola Kubes, Pineapple Kubes or Aniseed Balls would work too. Some boiled sweet suggestions here. Leave for a few days, remembering each day to give the jar(s) a little shaky shaky, maybe a tasty tasty...
The alcohol dissolves the sweets and leaves a syrupy liqueur-type drink. Decant into bottles and voilà a handmade Christmas gift that doesn't cost a fortune, is easy to make and looks fab in a little labelled bottle ready for gift-giving!
*Drink responsibly ;)
