To those asking about the koji palmiers--- I grew koji on rice, as you would to make miso, shoyu, etc. and I just cultured cream for a day or two with it. Shook the hell outa it and tada, butter. I tried to get a fair amount of the water out because for properly laminated doughs you need high quality, high butterfat content butter, which is usually 83% or above. This is so the layers stay intact between the layers of dough, rather than melding together (sad) or the butter sheets cracking (sad).
So yea, palmiers are just puff pastry with sugar and a little salt rolled into the final layers, and then coated in sugar so they get a bit carmelized. I fuck around with puff pastry a lot because I make bourekas a lot and they need a seriously light puff pastry to be special and cloudy.
Koji butter has slightly more umami flavor than standard cultured butter. This works well in baking---that's why miso is so nice in cookies.
When making puff you can do a standard puff, which includes a butter "lock in" that is enveloped into a very simple dough and then laminated. Or you can do an inverted puff, where the butter is on the outside, wrapped around the dough. This one requires a bit more practice and speed to get down.
For a classic smallish batch of puff you can use:
280g flour (I do 50/50 bread and APF)
130g water
28g butter-- tempered that goes into the dough
1 tsp salt
1/2 tsp lemon juice (or slightly more)
225g high quality butter (Kerrigold works or any other nice butter which cite their butterfat content or koji butter if you're into that kind of thing) and a sprinkle of flour for the lock in
Anyway I won't write through the whole shebang but I'm happy to if anyone actually wants to make them.
Oh and here's some bread in case that was boring. It's sourdough and uses T85, red bug wheat, and graham flour.
