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.
