Ripe summer peaches need a strong pie crust. Even with the advantage of tapioca and an egg white finish, peaches right off the tree are too juicy to be contained in a thin, dry pastry that might be perfectly suitable for winter apples. Someday I’ll have an outdoor wood-fired oven and then during the long, slow cool-down of a bread fire I’m going to dry some peaches and make pie with the soft, withered fruit. I bet that will be outstanding.
For the crust: put 4 C white flour, 2 tsp salt, 2 tsp sugar, and 1/2 tsp baking powder in a food processor and pulse a few times. Add 1 C cold unsalted butter (two sticks) cut into 1/2″ pieces, pulse just until there aren’t any large chunks. Mix 1/2 C very cold water with 2 tsp of good quality cider vinegar and add to the processor bowl by tablespoonfuls as you pulse. You want the pastry to just begin clumping together, but not be totally wet.
Dump the contents of the bowl out onto a large piece of wax paper. The dough will be crumbly and not entirely cohesive. Push it together using the ends of the sheet of wax paper. Cut the lump of crust in half with a bowl scraper or a large knife, pile one half on top of the other and squish them gently together. As you do this a few times the crumbs at the edge will gradually be incorporated and the crust will have lovely layers, like danish pastry. Cut the lump almost in half once more (you want one piece slightly larger to be the bottom crust, the top will use less), wrap each piece in some waxed paper, put both pieces into a plastic bag and refrigerate for half an hour, or overnight.The vinegar and baking powder make a very soft, resilient crust that rolls out beautifully and doesn’t crack or develop holes where the fruit pokes up.
Now go pick some peaches.
I confess that while my pantry is stuffed with wonderful cookbooks full of pie recipes, including handwritten ones from family members, the only recipe I use for fruit pie is the one on the back of the Minute tapioca box. It works every time, adds nothing objectionable to the basic fruit and pastry, and is incredibly easy – what more could one ask? I’m also fond of the idiosyncrasies. The box lists instructions for apple (sliced), blueberry, cherry, peach (sliced), and strawberry rhubarb. Did someone, somewhere, put whole apples or peaches in a pie?
Preheat the oven to 400 F. Separate an egg and pour the white into a small dish or a coffee mug.
Following the instructions for peach pie, add 1/4 C tapioca, 3/4 C sugar and 1 Tbs lemon juice to 4 C of (sliced) peaches. Mix gently and let stand for 15 minutes while you roll out the crust. Cover the bowl with plastic wrap or a dishtowel because fruit flies will arrive out of nowhere to have some of this stuff.
Retrieve the dough from the fridge. If it’s very hard, give it a minute to soften slightly. Roll it out fit it to the pie plate, being careful not to stretch the dough. Cut the excess off the edge with a pair of kitchen shears, and make a pie tail with the “leavings” that you wish you could mail to the Boy who is at university. Sadly, it doesn’t travel well.
If your peaches are really juicy, pour about 1/4 C of liquid off before you dump the fruit into the bottom crust. Dot with a Tbs of butter cut into small pieces. Brush egg white on the edges of the bottom crust and gently lay the top crust over it. Again, try not to tug or pull on the dough. Trim the edges close to the pie plate again with shears. Press all around the pie with a sharp-tined fork to seal. Cut a few holes in the top crust and brush all over with egg white. Sprinkle a tsp of sugar over the top for a slightly crunchier crust.
Bake the pie at 400 F for about 50 minutes or until the crust is golden brown and fruit juice is bubbling in the vents. If the pie tail is small you may have to take it out at 45 minutes.
