In the bowl of a stand mixer fitted with the paddle attachment, whisk together the pizza flour and instant yeast until well-combined. Whisk in the salt until evenly distributed.
Add the water, vinegar, 3 tablespoons olive oil, and honey. Mix on low speed with the paddle attachment until a very sticky batter-style dough forms.
Turn the mixer to medium-high speed and mix for 4 minutes. The dough will still be quite thin and very sticky, but should have thickened a bit.
You can work with the dough right away, or allow it a cold rise first for flavor development.
For a cold rise, transfer the dough to a greased 2-quart proofing bucket with tight-fitting lid or a bowl at least 2-quarts in volume, and cover tightly with plastic wrap. Place the bucket or covered bowl in the refrigerator for at least 1 hour and up to 2 days. It will expand, but remain very sticky.
Let the dough rise
On baking day, if you've chilled the dough, or right after mixing, prepare the dough for its (final) rise.
Drizzle enough olive oil to cover the bottom of a 9-inch x 13-inch x 2-inch pan with 1/8-inch of oil. Turn the pan slowly to spread it evenly around the surface of the pan, including greasing the sides.
Use a greased silicone spatula to scrape the dough out of the mixing bowl (or proofing container if you refrigerated it) into the oiled pan.
Drizzle the top of the dough lightly and your fingers generously with more oil. Use your fingers to press and push the dough into a rectangle about 9-inches x 13-inches, filling the pan, in a single layer.
For a more even layer, use an oiled bench scraper or cake turner to smooth the top of the rectangle as much as you can.
Cover the top of the pan with oiled plastic wrap and place it in a warm, draft-free location to rise until at least doubled in size. This will take 2 to 3 hours.
Bake the bread
When the dough is nearly at the end of its rise, preheat your oven to 425°F.
Uncover the pan with the risen dough, drizzle the top evenly with about 2 tablespoons of olive oil, then oil the tips of your fingers generously.
Dimple the dough by pressing the tips of your fingers into the dough straight down to the bottom of the pan in about half-inch intervals from one short side to the other.
Drizzle the dough lightly with more oil if it isn’t already glistening. Place the pan in the center of the preheated oven and bake for 15 minutes.
Reduce the oven temp to 375°F, and bake until the bread is lightly golden brown all over, most of the oil has been absorbed, and the internal temperature an instant-read thermometer inserted in the center reads at least 205°F (another 20 to 25 minutes).
If the top is browning too quickly, cover with aluminum foil until finished baking.
Remove the pan from the oven, remove any foil you’ve added, and place the baking pan on a wire rack.
Let the bread cool for 5 minutes in the pan. Remove the pan and place the bread right on the rack to cool for another 30 to 45 minutes to let the starches in the bread set.
Slice with a large serrated bread knife and serve.

Notes
About the flour blend I have made this recipe successfully using King Arthur Flour ("KAF") Gluten Free Pizza Flour, Caputo Fioreglut, and my gluten free bread flour recipe.The KAF gluten free pizza flour makes the bread with the largest holes, and the best interior texture. Caputo Fioreglut makes smaller holes with great outside texture and the last amount of flavor.My bread flour blend browns the best and has the best overall flavor, but I think would work better with another 1/4 cup (2 fluid ounces) additional water. Nutritional information Is approximate based on 1 of 6 equal individual servings, and does not include olive oil used for drizzling.
