Texas Peach Cobbler

Many southern states can serve peach cobbler (something like a peach pie), but Texas peach cobbler contains Texas peaches. “Cobbler” was known in the United States from at least the early 19th century, and “peach cobbler” was known soon after that. “Texas peach cobbler” has been famous since about 1900.
     
 
Wikipedia: Cobbler (food)
Cobbler is a traditional dish in both the United States and the United Kingdom, although the meaning of the term is quite different in each country. In the United States, it is usually a dessert consisting of a fruit filling poured into a large baking dish over a batter that rises through when baking. The batter forms as a dumpling within the cobbler as well as a crust for the top. In the United Kingdom it is usually a savoury meat dish, typically a lamb casserole, which is covered with a savoury scone-like topping—each scone (or biscuit) forming a separable cobbler. Fruit-based versions are also increasingly popular in the United Kingdom—although they still retain the separate cobbler (or biscuit) topping of the meat version—and savoury or meat versions are not unknown in the United States.
 
Cobbler Fillings
American Cobblers are usually filled with fresh fruit, such as apples, peaches, blackberries, or cherries. British cobblers are filled with a meat and vegetables and served as a main course. The British version is more like a casserole covered with individual cobblers (or scones); the classic British filling is lamb.
 
Varieties
In the United States varieties of cobbler include the Betty, the Grunt, the Slump, the Buckle, and the Sonker. The Crisp or Crumble differ from the cobbler in that the cobbler’s top layer is more biscuit-like. Grunts and Slumps are a New England variety of cobbler, typically cooked on the stove-top or cooker in an iron skillet or pan with the dough on top in the shape of dumplings—they reportedly take their name from the grunting sound they make while cooking. A Buckle is made with yellow batter (like cake batter), with the filling mixed in with the batter. The Sonker is unique to North Carolina: it is a deep-dish version of the American cobbler.

POMOLOGICAL.
Forth Worth Star-Telegram: Peach cobbler will top the East Texas menu all season, not to mention a tolerably fair portion left over for the clamoring customer east of the Mississippi. Peach cobbler is a joyous factor in fat living, as it obtains in Grand Old Texas, where the thrifty homeseeker is always welcome.
 
And on top of the peach cobbler, a bowl of peaches and cream fits like a skullcap; and when superimposed upon peaches and cream a snifter of peach-and-honey is said to make a common man feel like a standpipe full of purple joy. Come to Texas.
