01 - In a medium saucepan, combine water, butter, sugar, and salt. Bring to a boil over medium heat. Add flour all at once, stirring vigorously with a wooden spoon until the mixture pulls away from the sides and forms a ball, about 1–2 minutes. Remove from heat and let cool for 5 minutes. Beat in eggs one at a time, fully incorporating each before adding the next. Stir in vanilla extract. Transfer dough to a piping bag fitted with a large star tip.
02 - Cut parchment paper into 8 squares, approximately 4x4 inches each. Pipe dough rings about 3 inches wide onto each parchment square.
03 - Heat 2 inches of vegetable oil in a deep pot to 350°F. Using a spatula, gently lower each parchment square dough-side down into the hot oil. After a few seconds, remove the parchment with tongs. Fry crullers 2–3 minutes per side until golden and puffed. Drain on paper towels and let cool completely.
04 - Mash the strawberries and press through a fine-mesh sieve to yield about 2 tablespoons of juice. In a bowl, whisk together powdered sugar, strawberry juice, lemon juice, and just enough milk to form a smooth, pourable glaze.
05 - Dip the top of each cooled cruller into the glaze. Set on a wire rack and let stand until the glaze firms up, about 30 minutes.
