In medium saucepan, combine milk, water, butter, sugar and pinch of salt.
Bring the mixture to a simmer over medium heat
Add the flour all at once. Stir until the dough pulls away from the sides of the pan and forms a ball. Remove from heat and let cool for three minutes.
pour into a mixer add while mixing on low add egg one at a time. Thoroughly mix between each addition. You may use more or less, your looking for a smooth glossy dough that when you plop some off the spatula it will leave a nice thin, smooth peak
Use a large round tip to pipe two to three inch lines onto parchment-covered baking sheets.
carefully brush with water or an egg wash to remove imperfections (water will eave the cream puffs normal looking, beaten egg will leave it glossy)
Bake in 425 degree oven for ten minutes.
Decrease heat to 350 degrees. Do not open the oven door. Bake for thirty minutes (depending on size check at 10 and 20).
In the last 5 mins of baking pierce the bottom with a skewer or chopstick to allow steam to escape and dry out the inside (I do 2-3).
Let cool.

Reduce the heat to low and stir constantly for about 3 minutes until very thick and smooth and the flour taste has been cooked out.
