Fruit Cobbler

My grandmother often made this dessert. It is a wonderful, warm, comfort food.

Heat in a saucepan, and pour into a 9X13" pan:
6 c blackberries (or peaches, raspberries)
3/4 c sugar
1 t lemon juice
1/4 t cinnamon
2 T cornstarch

In a separate bowl, make a dough by mixing:
1 c flour
1 T sugar
1 1/2 t baking powder
1/2 t salt

4 T shortening
1/2 c milk

Drop dough by spoonfuls on fruit. Bake at 400 for 30 minutes.
