Here's the 1948 recipe for Old Style Peach Cobbler.
2 1/2 cups sliced canned cling peaches
3/4 cup canned cling peach syrup
1/4 cup brown sugar (packed)
1 1/2 tbsp. cornstarch
Few grains salt
1 tbsp. granulated sugar
1/8 tsp. baking soda
1 cup prepared biscuit mix (or your own biscuit recipe)
1/3 cup cultured sour cream
2 to 3 tbsp. milk (if needed)
Sweet or sour cream for topping
Place peaches in bottom of a 1-quart casserole. Mix peach syrup, brown sugar, cornstarch and salt. Pour over peaches. Set casserole in hot oven (425˚) while mixing dough. Stir sugar and soda into biscuit mix. Add cream and milk to make soft dough; mix lightly. Place by spoonfuls on top of hot peaches. Bake 30 to 35 minutes until well browned. Serve warm with sweet or sour cream. Serves 6 to 8.
