Ruth says you can peel peaches by dropping them into boiling water for 40-60 seconds and then running them under cold water until your hands are no longer burning. Then you slip the skins off and drop them into the dish, juice and all. I use pears, simply peeling and chunking them up a bit.
Add lemon juice to the fruit.
Combine the sugar and the cornstarch, and stir into the fruit.
Combine the flour, baking powder ,baking soda, and the salt.
Cut in butter.
Mix in buttermilk.
Set the dough over the fruit. It won't be perfect. It won't be pretty. BUT it will be amazing. Remember, the topping will rise during baking, so it will cover a little more than it does pre-baked. It is NOT meant to completely cover the whole thing, FYI. Part of the appeal is seeing some fruit here and there.
Bake at 400* for 30 minutes or until golden brown.
Serve with heavy cream on the side. I drown mine (our oldest says I eat pear cobbler soup).
It's best served warm on the day it's made. Hide leftovers in the fridge so you don't have to share.
