Strawberry Cream Puffs with Strawberry Sauce

Preheat oven to 375 °F. Line baking sheet with parchment paper. Combine water, butter, salt and sugar in heavy medium saucepan. Bring to boil, stirring to melt butter. Add flour; using wooden spoon, stir vigorously until mixture clumps together, forming ball. Stir 1 minute longer. Remove from heat. Transfer dough to medium bowl. Using electric mixer, add eggs 1 at time, beating until dough is smooth after each addition (dough will be slightly soft and shiny). Using 1 rounded tablespoon dough for each cream puff, spoon dough onto prepared baking sheet, spacing about 2 inches apart and forming mounds about 3/4 inch to 1 inch high and 1 1/4 inches in diameter. Using moist fingertips, gently press tops of cream puffs flatten any peaks. Bake until golden brown, about 37 minutes. Transfer baking sheet to rack; let cream puffs cool. (Can be made 4 hours ahead. Let stand at room temperature.)
