Combine yeast mixture ingredients and let the yeast activate for about 10 minutes. Set aside.
Mix water roux ingredients in a small pan and heat on a stove top until the mixture is thickened or about 2-3 minutes. Set aside.
Mix flour mixture ingredients together, then add yeast and water roux ingredients. Mix together well for a few minutes in a food processor to make a bread dough.
Heat oven to 350°F/180°C.
Grease a bread pan with butter and add the bread dough. Let sit on top of the stove (which is heating up) for about 30 minutes.
When bread dough has risen, carefully place in the oven and bake for 25 minutes.
Take the bread out of the bread pan and place on a baking sheet, then bake for an additional 15-20 minutes at 350°F/180°C. This seems to cook the bread more evenly and gives the edges a nice crispy texture.
When done, take it out of the oven and let it cool down. Don’t cut it while hot.
