5 c. gently rinsed wild blueberries
3 c. sugar
1/4 - 1/2 c. Curacao

Mix berries and sugar in large pot. Heat gently until sugar melts. Add Curacao and boil gently 20 to 30 minutes until a drop placed on a clean dry plate tends to stay put when plate is slightly tilted. If it runs very easily, it's not done. Another test is to pour the jam off a large spoon. If it makes two smallish streams rather than one large one, it's done. Be patient. Pour hot jam into hot sterile eight ounce jars with discs and rims. Make about four to five jars.
