Place blackberries in large covered pot, add 1/2 cup of the sugar and water and
bring to a boil.
Meanwhile, in a small bowl, mix baking mix, milk, egg, oil and remaining 1/2
cup sugar to form a dough, not as thin as pancake dough and not as thick as biscuit
dough, to be dropped from spoon.
Drop by spoonful into boiling berries, spacing over top of pot. Reduce heat immediately
to medium low and cover. Steam for approximately 15 minutes. Do not remove lid for
first 15 minutes so dumplings will cook through.
