Combine the warm water, yeast, and honey in a small bowl. Stir gently and briefly to mix everything, then let it sit for about 5-10 minutes until the yeast becomes frothy.
Combine whole wheat pastry flour and salt in a large mixing bowl. Whisk well to distribute the salt evenly through the flour.
When the yeast is ready, make a well in the center and pour in the yeast mixture and olive oil.
Mix the ingredients together until a wet dough forms. If you need to add a small amount of extra water to reach the proper consistency, do so. This should be a wet dough that does not mix into a firm dough ball.
Cover the bowl with a clean kitchen towel and let it rise in a warm place for about 1½ hours or until the dough doubles in size. I set mine in my unheated oven. Just remember to pull the bowl out before you turn the oven on for baking.
Preheat your oven to 425°F (220°C). Grease a baking sheet or cast iron skillet or line it with parchment paper. In hindsight, I would do both. Despite oiling the pan, the bread did still get stuck. So parchment and oil together are a safe bet for easy loaf removal.
Pour and scrape the dough into the prepared baking dish and gently distribute it over the surface of the dish or pan. This is done easily by stippling the dough with your fingers to move the dough into place. Make sure it's more or less even so that it bakes evenly. You are using your fingers to also create dimples on the surface of the dough.
Drizzle some oil over the top and sprinkle your favorite toppings on. Most toppings will need to be gently pressed into the surface of the dough. And don't forget to finish with a light dusting of salt.
Your dough is now ready to bake. Place the bread into a preheated oven and bake for about 25-30 minutes or until the focaccia turns golden brown on top. In some cases, it may only need 15-20 minutes of baking. So keep an eye on it the first time you make this. Check the bread at the last 10-minute mark. If it's not as brown as you might want, you can raise the temperature up to 450 F. for the last 10 minutes of baking. On the other hand, if the top is getting too brown, you can cover the dish with a loose piece of foil. Much of this will depend on what you top your bread with.
Remove the focaccia from the oven and let it cool before slicing and serving. Enjoy it warm or at room temperature as a delicious accompaniment to soups, salads or as a standalone snack.
