Dough – How to use pie weights

Damn, that looks good. I've never made this particular type of bread before, but here are some things that I do know which might help:

Butter is (roughly) 10% water and 90% fat, while lard is 100% fat. So if you substitute one for the other, you should adjust the amount of water in the recipe accordingly. The flavor will be a little different, but I bet either one would work.

I would not assume AP flour. In fact, I'd assume high-gluten bread flour. The gluten is what creates those fibers. It's the fat that keeps it tender.

This looks very similar to a brioche, so you might want to look at brioche recipes to learn some of the principles. One thing that most of them will tell you is to to knead the dough to develop the gluten fibers, and then add the butter. This I think is the key. I know that fat can keep gluten molecules from sticking together into strands, so if you add the fat later, you should wind up with strands of gluten surrounded by fat.

When you have a (good) bread recipe, the weight ratio is always given as percentage of the flour. This tradition is known as a baker's percentage. It may sound counterintuitive at first, but when you are measuring, or scaling, ingredients (which add to the total weight by themselves) you soon notice how convenient it is.

So, if you recipe calls for 300 g flour and 3% salt, it needs 9g salt. The water at 150 ml is 50% - a rather low hydration, don't do this with bread flour unless you have another liquid in the recipe you didn't mention (eggs, oil, or additional water for a poolish). It will be stiff with AP flour, but I like it that way, while other people find it too hard. It is up to personal preference, I guess. Also measure the other ingredients (yeast) as a percentage of the flour weight. And if you are given a recipe for fresh yeast, don't forget to convert it to instant dry if you are using it, or vice versa - the conversion factor is 3:1.
