Press down with your knuckles to create a uniform surface and to push out air.
At room temperature, it typically takes 7-9 hours for this sweet stiff levain to be at peak.
In a sauce pan set on med-low heat, whisk the milk and flour until blended. Then cook for several minutes until thickened, stirring regularly with a spoon or heat-resistant spatula. Let cool in the pan or, for faster results, in a new bowl.
In the bowl of a stand mixer, briefly whisk the dry dough ingredients, and then add the sweet stiff starter, separating it into 5-6 portions as you add it to the bowl.
Now pour/scrape in all the wet ingredients (including the tangzhong), with the melted butter last. With the dough hook attachment, mix on low speed for a minute, scrape down the sides, and then mix on medium speed for 15-20 minutes. The dough will seem very soft, but as you approach the 15-20 minute mark, it should not stick to your hands and should pass the windowpane test.
Transfer the dough to a lightly oiled bowl, form it into a ball, flip it smooth side up, cover and let rise for 6-12 hours depending on room temperature. You can place the dough into the fridge to chill the dough for about 1.5 hours, this makes rolling the dough easier.
Prepare your pans by greasing them or line with parchment paper.
Scrape the dough out onto a clean counter top. Lightly flour the bench. Press the dough into a rectangle and divide it into four. Shape each tightly into a boule, allow to rest 5 mins. Using a rolling pin roll each ball out and then letterfold. Turn 90* and using a rolling pin roll each out to at least 8”. Roll each into a tight roll with some tension. Arrange the rolls of dough inside your lined pan alternating the direction of the swirls. This should allow a greater rise during proof and in the oven.
Cover and let proof for 2-4 hours (more if you put the dough in the refrigerator). I proof until the top of the dough comes to within 1 cm of the top edge of the pan.
Preheat the oven to 350F and brush the dough with the egg-milk wash.
Bake the loaves for 50 minutes or until the internal temperature is at least 190F. Shield your loaf if it gets brown early in the baking process. After 50 mins remove the bread from the pan and bake a further 10 mins by placing the loaf directly in the oven on the rack with the temperature turned down to 325ºF. If you loaf is super tall like mine was, I gave it another 7 mins with the oven turned off to really ensure that the side crust was firm enough to hold its shape. You can brush the top of the loaf with butter if you wish at this point while the bread is still hot.
