In saucepan, combine water, butter, sugar and salt and bring to a full boil on medium heat.Add flour all at once and stir vigorously with wooden spoon/electric hand mixer, until smooth THEN stir faster! The paste will then start to turn dry and not cling to spoon or sides of pan. *Don't overcook or over stir, or dough may fail to puff. Cool for 5-10 mins. With hand mixer add 4 eggs, one at a time, ensuring paste is smooth and shiny before adding next egg.
Preheat oven to 400 degree Fahrenheit.
Use pastry bag or simply drop spoonfull of paste onto ungreased baking sheet.Before baking, lightly spray water overpuffs for light airy texture. Bake 10 mins at 400, then reduce to 350degree Fahrenheit for 25 mins more until golden brown and very firm to touch.
Cool completely on rack.
Then fill with favorite cream and mixberries and dust tops with icing sugar. Enjoy!
