Generously grease the 2 loaf pans with butter or butter alternative. Set aside.
Using a liquid measuring cup, measure 1/2 cup of water and add the maple syrup (or other sweetener) and the yeast. Mix well.
Pour the sweetened yeast water into the bowl with the soaked flour. Mix well.
Sprinkle the salt into the bowl. Mix well.
The batter should be quite loose, but if it appears too watery, add some all-purpose or bread flour to the bowl 1/4 cup at a time and mix well until you reach the proper consistency. (See video for the desired consistency.)
Loosely cover the bowl and allow the soaked flour to rest in a warm location for 1 1/2 hours if using instant yeast or 1 3/4 hours if using active yeast.
After the resting period, gently pour the batter, equally divided, between the two greased loaf pans.
Allow the batter to rise in the loaf pans, but do not allow it to rise past the rim of the loaf pans. Approximately 45 minutes.
Place the loaf pans on the middle rack of a 350°F (177°C) preheated oven and bake for approximately 40 minutes until the bread appears to be golden brown. If, at 30 minutes, the bread appears to be over-browning but not completely baked, tent it with aluminum foil and continue to bake.
Once the bread is baked, remove the loaf pans from the oven and place them on a heatproof surface. Using potholders, remove the bread from the loaf pans and transfer them to a cooling rack.
Cool completely before slicing.
Well-wrapped, Soaked Flour Bread can be stored in the refrigerator for 2-3 days and in the freezer for 2-3 months. It is best enjoyed toasted when coming right out of the refrigerator. If being eaten when coming out of the freezer, allow the frozen bread to defrost, come up to room temperature, and then toast it.
