There are several ways to pick the perfect fresh peaches for this recipe. Find fruit that is heavy for it's size, firm to the touch when you give it a very gentle squeeze, and smells like a peach when you sniff it. Too-soft peaches are harder to slice but can still be used. Too-firm peaches really hold their shape during baking and can still be used. This cobbler is a very forgiving recipe, so almost any peach will do.
