Why would you buy something when you can make it cheaper with very little trouble? Here's a self rising crust that's great for cobblers. For meat pies, just omit the sugar!
1 cup flour
1/2 cup sugar
2 teaspoons baking powder
1 TB oil
Enough milk to make a thick but pourable batter.
Mix it all up and dump it in a baking dish, put the fruit in on top (two cans worth) and bake about an hour at around 400 degrees.
