Prepare a sponge. In a large mixing bowl, combine warm water, yeast, ⅓ cup of honey and 4 cups of flour. Stir until combined, cover and let rise for 30 minutes in a warm location.
The dough should have doubled in size by now. Add 2 ½ cups more flour, the remaining honey, melted butter and salt. Mix well. Knead for five full minutes, by hand or in a stand mixer with dough hook attachment. If the dough feels excessively sticky, add another ½ cup of flour.
Place the dough ball in a greased bowl and let rise for 30 minutes. Preheat oven to 400℉. Spray the Pullman pan generously with cooking spray.
Punch the dough down to remove air bubbles. Form the dough into a large rectangle that is the width of the pan. Roll the dough like a cinnamon roll and place it in the pan, seam down. Let rise until double.
The dough is ready when you can poke a corner of the loaf and an indention remains, like this picture. I've included a photo in this post if you aren't sure what I mean. Check it out! Turn then oven temperature down to 350°.
Put the bread in the oven and bake for 50 minutes. The loaf is done when the bottom is lightly brown. If the loaf gets too brown on top, cover with foil. The internal temperature should be 190℉ when the loaf is cooked through.
Immediately invert the loaf onto a cooling rack when it comes out of the hot oven. Resist the urge to slice a piece of bread until it has completely cooled.
The bread can be stored in an airtight container on the counter for up to a week, no refrigeration necessary. This big loaf sandwich bread can also be frozen after it has fully cooled. It will be good for up to three months!
