Slab Pie Recipe Made with Blueberries and Einkorn Flour (2024)

FAQs

How to keep blueberry pie from being runny? ›

How do I keep a berry pie from being runny inside? Berry pies need starch to help thicken the filling because berries give off a lot of juice when they cook. For a typical nine inch pie, you need two tablespoons of flour, cornstarch, or tapioca starch.

Meringue pies will ''weep'' water because of the interaction between the filling and the whipped meringue. If one or the other is overcooked, water beads will form and weep. Egg whites can also weep if they are over-beaten or are from old eggs. Refrigeration (unfortunately) speeds up the process of weeping—oops!

But if that is simply the nature of the recipe, simply make sure your crust is good and brown and that a knife inserted in the center of your pie meets no resistance. Are you sure you have a good juicy filling but not sure why your pie is not bubbling yet? Make certain that your center vents are open!

We like tapioca in blueberry, cherry or peach pies. Arrowroot, unlike cornstarch, is not broken down by the acid in the fruit you are using so it is a good choice for fruit with a higher content of acidity such as strawberries or blackberries.

All-purpose flour is an easy solution, as you're sure to have it in your pantry. Since it's lower in starch, you'll use more of it than you would higher-starch thickeners. Quick-cooking tapioca makes filling bright and clear, but also gives it a stippled and somewhat sticky texture.

Brush the Bottom with Corn Syrup or Egg White

Coating the inside surface of the bottom crust will create a barrier to prevent sogginess.

Experiment with different thickeners

If you usually use flour to thicken your apple pie and it's not doing the job, try something different: cornstarch, tapioca, and arrowroot are other established fruit pie thickeners. For more on specific thickeners and how to use them, see our Pie Filling Thickeners Guide.

Most say the pie is done if the crust is brown and the filling is bubbling. The truth is it needs to bubble for at least 6 to 10 minutes to properly cook the fruit. This depends on how ripe the fruit was, how thin it was cut and the variety of the fruit.

If it's not bubbling but looks perfectly golden, turn the heat down to 350 degrees F and give it another 8-10 minutes. Let the pie cool completely before slicing, so the juices have time to thicken; at least 4 hours, preferably more.

Pay attention to bake times: one reason you'll often end up with a runny fruit pie is simply that it hasn't been baked long enough. Any thickener you use needs a little time to set up, and people often see their crust turning light brown and think the pie is done when it's really not.

How do you keep pie filling from being runny? ›

The best way to thicken runny apple pie filling before baking it is to add some cornstarch, tapioca starch, or flour to your mix. To fix a runny pie that's already been baked, simply let it cool to see if it will congeal naturally. If not, you can stick it back in the oven for a bit longer.

Tapioca-it's not just for pudding! This old-school ingredient may be what your great grandmother used to thicken her pies, and it's still great for making a perfect fruit pie with a clear, stable filling. Tapioca is derived from cassava (also known as yuca or manioc), a starchy root native to South America.

If there aren't enough apples in your pie, it can lead to excess liquid as apples release moisture when baked. The filling might not thicken properly, resulting in a watery consistency.
