Japanese Milk Bread

This is a good one, meaning I've attempted it twice successfully. I mean like wow, right? twice.. amazing, yeah I'm kind of amazing.

so anyway

bechamel:
100ml milk
25 gr flour

dough:

• 330g flour
• the bechamel you just made
• 80ml milk
• 50gr butter (I didn't have enough so I did half butter half oil)
• 1 packet yeast (I think 5gr)
• 1 tsp salt
• 50gr sugar but no more
• 1 egg beaten

you'll first need to make a kind of bechamel:

put 100ml of milk in a saucepan and add gradually the 25 gr flour (yeah doesn't need to be too precise you know) - everytime you add the flour, it's best if you remove it from the flame. put on low flame while mixing constantly until you get something relatively thick. take off flame let it cool down someplace, but cover is so something is in contact with milky thing stuff.

then make dough

add the flower in a large bowl, then sugar, yeast, salt, mix well, add the milk, then the egg, and finally incorporate the butter. You're supposed to stuff it inside the dough and go on kneading it, I added half and half oil/butter, worked out perfect. anyway, keep on kneading as well as you can for a good 15/20 minutes. it should detach from surface now, and be very ellastic or elastic rather.
make a nice ball, put it to rest for a while, like 2 hours or even all night if you prefer. it should be covered of course.

then, take out the farts, the gas should I say, make a hole in the center, open upto create a long tube. cut it up in four equal parts. let it rest a little, covered.
then role them nicely and use a, damn what is it called? yes, a rolling pin to ellongate each ball into a kind of rectangle. fold in each side (lenghtwise) and then roll from one end, it should kind of resemble that little face thing they give you on japanese flights or hotels to wash you face, or hands I'm not sure...
anyway, let it rest for 10mn or so, and then do it again. second time, you can now place each little rolled flannel into your tin (a rectangular bread loaf one) it needs to be buttered and floured previously.
let this grow for a  couple of hours (covered) put in the oven 200 c for I think 25mn (my oven sucks) then cover it with aluminium foil and cook for another 20mn or less if your oven is better than mine.
