pre-heat oven to 400
boil water, milk, sugar, salt and butter in sauce pan
add flour and stir on heat until it makes a paste that detaches from sides of the pan
take off heat, put in new bowl
stir in eggs one at a time, rapidly, it will be clumpy, weird and then poof! will become a lovely batter. stir rigoriously until when you pull your spoon up the batter stays stiff and looks like little bird's beaks
transfer to a piping bag with large circular tip and pipe onto cookie sheet lined with parchment paper any shape you like
put pan in oven-TURN OVEN OFF- what? yep, turn it off for 10 mintues, then set it to 300F and bake for another 25 minutes- they will get golden brown and puffy
