Although time consuming to make... it is an item you can make and store in your refrigerator for several months and use it as needed!
1 lb powdered sugar
5 oz. Water
1/2 tsp of your favorite extract flavoring
Put the powdered sugar, water and extract into a heavy pan and heat on low, stirring continuously, until the sugar dissolves. Bring to a boil until your candy thermometer reaches 240ºF. Pour the hot syrup onto a cold wet working surface or marble board and let it cool slightly. Lift the edges of the syrup with a metal spatula and fold towards the center. Continue working around the syrup until the syrup forms a dense mass. Now it should be cool enough to work by hand. Knead like you would bread dough until you have a smooth white paste. Wrap and let cool completely before storing in the fridge. To use... Break off a piece in the size you need and place it in a bowl over a pan of hot water and heat gently until the mixture is the consistency of a thick cream. You may need to add some water or more flavoring.
