Whenever I taste a blackberry, I think of my grandmother's farm and the blackberry cobbler she used to make. I don't have her recipe (yet), but this is the recipe from the orchard/farm up the road where we pick blackberries (and peaches, apples, blueberries, pumpkins...).
4 cups fruit (peaches, berries, etc. peaches and apples must be peeled and sliced)
sugar to taste for fruit (I don't use any)
1 stick butter, melted
1 c. flour
1 c. sugar
1 c. milk
Place fruit and sugar in pie plate or baking pan; pour on melted butter. Combine flour and sugar; stir in milk. Spread crust over fruit. Bake at 350 degrees for 30-40 minutes or until light brown and fruit is bubbly.
