1 lb all purpose flour
1 tsp salt
It is super easy...
Melt the butter and set aside.
In a stand alone mixer with the hook attached, mix the flour and salt on speed 1.
Add the butter and egg. Add some water until you get a smooth and elastic texture.
Let it rest for 30 min.
Divide in 2 and roll each out to about 1/4 inch. Cut out circles 5 inches in diameter. (I use a pot lid)
