Why This Recipe Works
- A mix of wild and cultivated blueberries provides the filling inconceivable depth of taste.
- Tapioca starch forms a delicate-weight, certain gel that is rarely cloudy, slimy, or gloppy.
- A 4:1 ratio of fruit to sugar raises tapioca’s gelatinization point so the filling and crust will cook dinner at the identical price, that formula you never wish to interchange a thick filling for a soggy crust!
- Tempered-glass pie plates conduct warmth speedy and evenly to the dough, producing a much crispier crust than heavy ceramic or stoneware.
No topic what a particular obedient but totally unnamed source would prefer you affirm, image-favorable blueberry pie is ridiculously easy to acquire. That is in consequence of blueberries are not some mystery of the universe, full of variables no man can memoir for; they’re full of water. Tasty water, to make obvious, but water that will possibly perhaps even be precisely gauged in consequence of one thing identified as a scale.
Whether or not it’s unusual or frozen (more on that right here), a fruit’s weight provides us a legit indication of its water mumble, so we are succesful of without instruct predict how great starch is famous to create a gel and how great sugar is famous to present protection to that starch from thermal hydrolysis, a.okay.a. overcooking. Probabilities are you’ll possibly possibly possibly read up on the science at the wait on of my formula right here, but in put collectively all or not it’s needed to understand is that this: No topic your fruit, you need to possibly perhaps need 5.5% of its weight in tapioca starch and 25% of its weight in sugar, tossed in a crust, baked unless effervescent-sizzling, and cooled to 85°F (29°C). With those solutions, you need to possibly possibly possibly also always rely upon a pie that is juicy yet fantastically thick, never runny or gloppy.
Truth learn, or not it will not be relevant whether you need to possibly possibly possibly also just like bought blueberries, cherries, or plums, in consequence of water is the most titillating component we wish to memoir for by formula of thickening a pie. Nonetheless wait, you yowl. What about pectin? Would not that, cherish, like one thing to attain with pie?
Ehhh, not the truth is. For the uninitiated, pectin is a soluble fiber gift in many fruits, and when cooked it must reduction liquids to gel. It be most titillating natural to imagine this natural thickener must play a famous role in fruit pies, but pectin is a exiguous fussy, prepared to hang most titillating under particular stipulations. Besides concentration, which varies from fruit to fruit, pectin requires appropriate form the suitable amount of sugar, acidity, and warmth sooner than it must the truth is kick into equipment.
In accordance with my friend Cathy Barrow, author of Mrs. Wheelbarrow’s Engaging Pantry, pectin would not the truth is attain its thing unless about 220°F (104°C). That is properly above the interior temperature of any pie, significantly hampering pectin’s energy to gel. What’s more, when compared with jams and jellies, pie filling contains formula much less sugar and acid—two more components that decrease pectin’s role as a thickener.
So while or not it’s appropriate form that blueberries have a first price amount of pectin, or not it’s of exiguous exercise for the length of the context of a low-sugar, low-acid, low-warmth pie. Achieve merely, by formula of blueberry pie, pectin is totally inappropriate. That formula blueberry pie is ineffective easy to thicken, in consequence of there are not any wild cards to retain in mind.
Some bakers thicken their pies by cooking down the berries’ juice to concentrate the taste, but to me that makes for a jammy pie that is thick but additionally a exiguous dry. Others seize a pie so juicy it needs to be served with a spoon. My recipe provides the larger of both worlds: a blueberry pie that is lusciously thick and straightforward to gash, but with all its natural juices intact. It additionally wants a crispy, flaky, golden crust on the stop and bottom, without requiring any par-baking. Pointless to affirm, that will not be a feat any old fashion recipe can invent, but with my old fashion-customary flaky pie dough, you need to possibly perhaps never wish to danger a couple of soggy bottom crust all every other time.
Whether you to make a decision to head for a standard lattice pie or a elaborate herringbone crust, function not let anyone deliver you blueberry pie is a hit-or-jog away out proposition. I promise, or not it’s a surefire thing.
Manufacture the Simplest Blueberry Pie
20 oz unusual blueberries (3 1/4 cups; 565g)
8 oz wild blueberries (2 cups; 225g), unusual or frozen (see notes)
1 ounce unusual juice from 1 lemon (2 tablespoons; 30g)

Normal-customary flaky pie dough, rolled and chilled as per the instructions for a double crust
For the Egg Wash (optional):
1 astronomical egg
1 astronomical egg yolk
1/2 ounce heavy cream (1 tablespoon; 15g)
1/8 teaspoon (0.5g) Diamond Crystal kosher salt; for table salt, exercise half of as great by quantity or exercise the identical weight
To Relieve (optional):
For the Filling: Toss unprecedented and wild blueberries, lemon juice, sugar, salt, coriander (if the exercise of), and tapioca starch in a astronomical bowl, folding with a flexible spatula unless properly combined. Spot into prepared pie shell and top with closing dough, the exercise of a solid sheet, cutouts, or a lattice-top acquire. (Test out my tutorial right here.) Neat away excess dough and refrigerate to be particular top crust is totally chilled, about Half-hour. Meanwhile, regulate oven rack to decrease-center location and preheat to 400°F (200°C).
For the Egg Wash (if the exercise of): Spin egg, egg yolk, cream, and salt in a little bowl. Brush over chilled top crust in a thin, even layer. This will also just give the crust a bright, golden sheen, nonetheless it will not be a truly famous in any formula.
Location chilled pie on a parchment-lined half of-sheet pan. Bake unless crust is golden, about 1 hour, then loosely hide with tented foil. (Alternatively, an empty baking sheet can also be positioned on the topmost rack of the oven to reduction as a protect.) Proceed baking unless filling is effervescent even within the very heart of the pie, about quarter-hour longer. If crust totally covers filling, bake unless pie reaches an interior temperature of 213°F (101°C) on a digital thermometer. The time can vary considerably depending on the thickness and create of pie plate, the amount of top crust, how lengthy the pie modified into once refrigerated, et cetera.
To Relieve: Cool pie unless no warmer than 85°F (29°C) on a digital thermometer, about 3 hours depending on the create of pie plate (at larger temperatures, filling will most definitely be runny and skinny). Reduce into wedges with a inviting knife, urgent firmly against bottom and aspects of pie plate to be particular the bottom crust is totally minimize. Must you cherish, reduction with lemon chantilly. Wrapped in foil, leftovers will retain up to a couple days at room temperature; warmth 10 minutes in a 350°F (180°C) oven to revive crust sooner than serving.

Ensuing from disparate sourcing practices, tapioca starch manufactured in Asia could possibly perhaps just be derived from vegetation in its place of cassava, which can possibly perhaps just like different gelling properties. Opinion products that mention cassava by name on the packaging, akin to Bob’s Purple Mill.
Whether you need to possibly possibly possibly also just like bought enough local berries or hurry-of-the-mill grocery store fruit, smuggling a half of wild blueberries into the mix makes for a pie that is remarkably complex. Within the event that they assign not seem to be rising on your have backyard, seek wild blueberries within the freezer aisle of properly-stocked groceries cherish Kroger or markets akin to Complete Foods and Trader Joe’s. There’s no must defrost them sooner than the exercise of. Pointless to affirm, that will not be to affirm you need to possibly possibly possibly also’t acquire a wonderfully beautiful pie the exercise of cultivated blueberries by myself; most titillating that you just need to amassed potentially acquire two pies to taste the adaptation aspect by aspect. You realize, for science. Must you would seize to skip the wild blueberries, merely lengthen the “favorite” blueberries to 28 oz (5 2/3 cups; 795g), unusual or frozen.
Prep time will fluctuate depending on the complexity of crust acquire.
