From Classic Liqueurs, by Cheryl Long and Heather Kibbey:

This recipe is called Raspberry in their book, but a footnote states that the same recipe works for blackberries, blueberries, loganberries, snozberries and marionberries.

Crush berries with the back of a wooden spoon. Heat water and sugar together until completely dissolved. Pour warm syrup over berries. Stir.
