Instructions: Sterilize 4 half-pint canning jars. Bring water and sugar to boiling.

Add lemon, orange and raisins; simmer 5 minutes. Add blueberries and cook rapidly until thick, about 30 minutes. As mixture thickens, stir frequently to prevent sticking. Pour hot conserve into hot jars, leaving 1/4-inch head space. Wipe jar rims and adjust lids. Process 5 minutes in a boiling water bath.
