Baking naturally leavened bread requires a bit more planning on my part now since I've been storing my starter in the refrigerator. My cold starter likes to wake up by being fed at least twice over 24 hours before being used to build a levain. Sometimes I will feed it only once, then do a three stage levain build (using dabrownman's build ratios and schedule). Either way, I have to plan to refresh my starter, build the levain, and make the dough. Even though there is very little active hands-on time, it still takes a minimum of 36 hours from cold starter to hot bread.
So what's a gal to do when there's no more homemade bread in the freezer and she wants fresh bread fast? The answer is commercial bakers' yeast which, in my case, is instant dry yeast. I am not a fan of lean breads made with bakers' yeast. Even the long cold retarded ones lack the flavor, texture and character of those naturally leavened. But I do like enriched breads made with bakers' yeast. So I usually go with enriched when I want bread fast. [Since we're talking about homemade bread, fast is a relative term.]
I made the softest and fluffiest enriched bread a couple nights ago using Floyd's Hokkaido milk bread with tangzhong recipe found here. The only change I made was to decrease the sugar. I won't go into detail about the tangzhong method (aka water roux) since it's well documented on TFL, but I will say that it makes a difference in the bread's keeping quality. Today is day 3 and the bread is still soft and moist. I'm sure the butter, milk, sugar and eggs helped too, but I want to believe that tangzhong is magic.
One last thing...
This loaf is the opposite of what a German knight in the 1500s would have. Even if he did have something like this, it's so soft and fluffy that he would crush it with his iron hand.
