In a large bowl, combine the all-purpose flour, water, honey, molasses, salt, and instant yeast; stir until a sticky, shaggy dough forms.
Stir the dough about ten more strokes with the spoon to introduce a little air.
Cover the bowl with plastic wrap and let the dough rise at room temperature for 12 to 18 hours, until the surface is bubbly and the dough looks aerated.
When ready, lay a large piece of parchment paper on the counter and dust it lightly with flour.
Turn the sticky dough out onto the floured parchment; with lightly floured fingers or a spoon, fold it over itself twice to form a loose round.
Lift the parchment edges to place the dough (on the parchment) into a large bowl, cover with a kitchen towel, and let rise another 2 hours until doubled and springy.
About 30 minutes before the second rise is done, place a Dutch oven with its lid in the oven and preheat to 450°F (232°C).
Carefully remove the hot Dutch oven from the oven, lift the parchment with the dough, and place both into the pot.
Lightly score the top of the dough with a sharp knife, cover with the lid, and bake for 25 to 30 minutes.
Remove the lid and bake an additional 10 to 15 minutes until the crust is golden brown.
Transfer the bread to a rack and let cool at least 5 minutes before slicing.
