Whisk one ¼ oz envelope active dry yeast, 2 tsp honey, and 2 ½ cups lukewarm water in a mixing bowl and let it sit for 10 minutes.
Add 5 cups all purpose flour and kosher salt and mix with a rubber spatula until a shaggy dough forms and there are no dry streaks.
In a large bowl add 4 tbsp of the olive oil. Transfer the dough to the large bowl and turn to coat with oil. Cover with plastic wrap and let rise in the refrigerator for 8-24 hours until doubled in size. You can also let it rise at room temperature for 3-4 hours.
Butter a 9" x 13" baking pan. Add 1 tbsp olive oil to the middle of that pan.
Take the dough bowl and using 2 forks, lift the opposite side edge of the dough and fold over the center. Give the bowl a quarter turn and continue to fold the dough until it's deflated and formed into a rough ball. Transfer dough to the prepared baking pan. Cover with the remaining olive oil, and let rise, uncovered, in a warm spot until doubles in size, usually 1½ to 4 hours. The dough will be ready when, if you poke it with your finger, it springs back slowly leaving an indentation.
Preheat oven to 450°. Lightly oil your hands. Dimple focaccia all over, creating deep depressions in the dough. Be aggressive. Drizzle the dough with 1 tbsp olive oil and sprinkle with sea salt. Bake for 20-30 minutes.
[Optional] Prior to serving, melt 4 tbsp butter in a saucepan over medium heat. Grate cloves with a microplane and add to butter, cooking until garlic is lightly toasted. Brush garlic butter over focaccia and cut into squares for serving.
You can freeze focaccia bread. Reheat on a baking sheet in a 300° oven.
