Drain well and puree with a mixer for a few seconds with the butter.
Add the eggs, salt/pepper to taste.
Pate A Choux
In a saucepan, boil the water. Reduce to medium and add sugar and butter. When the butter is melted, add flour and salt. Stir quickly to form a ball.
Remove from heat. Cool 3 minutes and beat in eggs one at a time to form a thick dough. Add this to the potatoes and stir.
Place in a pastry bag and pipe round shapes onto a parchment lined pan. Brush with the egg wash and sprinkle with kosher salt or sea salt. Bake at 400 degrees for approx 30 minutes! Sprinkle tops with salt. Enjoy! I piped about 11 potatoes.
