I am making some pies tonight and took a couple of pictures during the dough making process.
This technique involves the high moisture and rest, autolyse process, which activates the gluten in the flour. This is the same technique used in the no knead bread recipe.
You add all the liquid and 3/4 of the flour, and then let it rest for 20 minutes.
Here we are after the initial mix.
After the 20 minute rest, I kneaded it for 5 minutes before adding the rest of the flour. The characteristics of the dough changes completely and it is almost cleaning the sides of the bowl.
I added the remaining flour (fourth cup -- actually last 160 grams out of 640 grams total) and kneaded for an additional 3 minutes.
This dough has 60% hydration and is still cleaning the sides and bottom of the bowl.
It is resting in the refrigerator and I will take it out an hour or so before the cook, depending on how much it rises while resting.
More pictures later.
