After talking about choosing apples for baking and then discussing the ingredients you need to make a pie crust, I now want to turn to bringing that crust into reality. That is the subject of this week’s Cooking Tip – how to make a great pie crust. As you read this Tip, you will notice that I often give you different recommendations. Everyone has their preferred method and I want to give you alternatives so you can find what works best for you.
The first point I want to make is COLD is your friend
when making pie crusts. The fat that you cut into the flour needs to stay solid
as long as possible so that once it is in the oven, it will melt at the
appropriate time creating steam and thus, the flaky layers we all crave in pie
crusts.
Start your pie crust by putting your flour and salt in a
bowl and whisk together. I highly recommend weighing your ingredients but if
not, measure carefully. At this point, if your kitchen is warm, you may want to
refrigerate the bowl/ingredients/equipment. Your aim (no matter the ambient
temperature) is a final dough temperature of 65°
to 70°. Yes, you can
take the temperature of your dough. Just one more reason to have a good digital
thermometer in your kitchen armamentarium.
SeriousEats.com points out that if your room temperature is above 73°, everything that touches the dough will warm it. You may have noticed that your dough seems to need less water on a hot day. That is because the butter is softer making it act more like a liquid. Although you may be tempted to use less water, this may lead to a weaker dough giving you headaches when you try to roll it out.
A solution is to chill everything with an aim to keeping your
dough temperature below 70°.
Take everything (your bowl with the dry ingredients, your rolling pin and your
pie pan) and put them all in the refrigerator. Your fat and your water should
already be in there keeping COLD until you need them. If your countertop
is warm, fill some plastic bags with ice water and place on the countertop to
cool it.
Next, add your COLD fat – butter, shortening or a combination.
If you are using a combination, cut up the shortening and add first. Mix it in
until the mixture is like sand. Then, add your butter, which should be cut into
small cubes, and toss gently in the flour. Working quickly, cut the butter into
the flour. I think no tool works as well as your hands to do this step although
you can use a pastry cutter. Using a snapping motion between your fingers and
thumbs, you will flatten out the butter cubes. Continue this until all the
butter is flattened. If your hands are warm, you may want to cool them under
the cold tap first. Do not overmix – you want to be left with an uneven mixture
with butter pieces that vary in size. Remember, this is what is going to give
your crust its flaky layers. So, you do not want your butter to melt or totally
disintegrate as you are doing this.
This is the point where you add the ICE water. One
train of thought is to never add all the water at once. Add it incrementally so
the dough does not get too wet. Start with drizzling in a few tablespoons and gently
tossing the mixture. A bowl scraper works great for this. Continue until the dough
holds together if you squeeze it in your palm. The reasoning for this is that
excess water can lead to more gluten development. However, a too-dry dough can
be very difficult to roll out.
Another point of view is that gluten is not necessarily the
enemy of soft, flaky crusts. Adding the water listed in the recipe all at once
and mixing until it comes together will give you a dough that is easier to roll
out without tearing.
After adding the water and mixing, empty the bowl onto a
very lightly floured surface or onto a piece of parchment paper. There are two ways
you can proceed from here. The easiest is to just gently gather the dough into
a ball. If it is still too dry, add more ice water but a small amount at a
time. A spritz from a spray bottle may be all you need. If you have added too
much water, sprinkle a bit more flour and gently mix it in.
A second way of finishing your pie dough is only slightly
more work but gives you even more flaky layers. For this method, you may want
to put your dough onto a piece of parchment. Press your dough into a rectangle
and then, using the paper to assist you, fold it into thirds – just as you
would a business letter – and then fold in half so it is square-shaped. If
necessary, using a water bottle, spritz any dry areas with the ice water and then
fold. You can also do this folding without parchment by putting your dough onto
a floured counter and use a bench scraper to help with the folding.
At this point, shape your dough into the shape of the pan
into which you will put it. This will make it easier to roll out to the correct
shape. If you have made enough dough for a double crust, cut the dough in half
before shaping. Some recommend rolling the shaped dough’s sides along a floured
surface to smooth the edges.
The next step varies by which expert you prefer to follow.
One recommendation is to wrap your dough into plastic and put in the
refrigerator for a minimum of 30 minutes. This hardens the fat, which has warmed
and softened during the mixing process. It also allows the gluten to relax. You
may wish to freeze the dough at this point for use at a future time. If so,
wrap in plastic and then in foil before putting in the freezer.
When you are ready to actually assemble your pie, remove the
chilled crust from the refrigerator. If it has chilled longer than 30 minutes,
you may need to let it warm up just a bit on the counter, leaving it wrapped.
It needs to be soft enough to roll but should still be cold to the touch. As
you roll it out, you should see large pieces of flattened butter.
Since rolling the dough “wakes” up the gluten and softens
the butter, a different recommendation is to roll out your dough and put it in
the pan right after you make it. Then, chill it thoroughly in the pie pan –
about two hours.
Transferring it to the pan can be done by folding the rolled-out
dough into quarters, placing it in the pan and unfolding it. Another method is
to gently roll the dough around your rolling pin and then unrolling it over
your pan.
You are now ready to finish your pie, right? No, remember
the word I mentioned in the beginning – COLD. You want to chill your pie
crust before filling it. Once again, this chilling helps to solidify that
wonderful fat as well as minimizing shrinkage during baking.
Some just recommend refrigerating the dough after being put
in the pie plate. As you have mixed and rolled out the dough, the gluten strands
that have developed are stretched and want to snap back. You have probably seen
that as you roll your dough; it doesn’t always stay but tends to shrink. Resting
the dough allows the tension in the strands to ease so they remain stretched
and don’t shrink back when heated. However, as the pie is baked, the dough is
not well set by the time the butter vaporizes. So, the air pockets created by
the steam when the butter melts disappear. The soft, not-yet-set dough sinks
into those spaces resulting in less flakiness.
Others recommend freezing the dough before baking. As you
bake frozen dough, it heats up and sets relatively quickly in comparison to the
time it takes the butter to melt. By the time the water in the butter starts to
turn to steam, the dough is well into its setting stage. The air spaces
occupied by the frozen butter, now that it has largely turned to steam, hold
their shape because the dough has started to set. Thus, flakier layers. The
downside is that as the water freezes, it holds the stretched gluten in place
rather than allowing it to relax. So, when you bake it, the gluten strands snap
back and the crust shrinks.
Many recommend a compromise by first refrigerating the dough
for approximately 40 minutes to relax the gluten to minimize shrinkage followed
by putting it in the freezer for 20 minutes to improve flakiness. Yes, this
does require a bit more timing but could lead to a superior result.
Now you are ready to choose your favorite filling. However,
before putting your filling in the pan, stop and ask yourself if you need to par-bake
your crust. Stay tuned for next week’s Tip as we delve into what par-baking is,
when you need to do it and how to par-bake. See you then!
