**The Art of Making Perfect Donuts with Chilled Custard Filling**
Making donuts from scratch requires precision, patience, and attention to detail. In this article, we will guide you through the process of creating perfect donuts with chilled custard filling.
**Preparing the Custard Filling**
To start, we need to prepare the custard filling. Begin by heating milk on low heat and slowly bringing it to a bare simmer in another small saucepan. Add egg yolks and sugar to the mixture, whisking until the mixture turns pale yellow. Next, add vanilla extract to the egg mixture and stir well. Then, add cake flour and combine the mixture well. When bubbles start to appear around the edges, temper the eggs by gradually adding a small portion of the hot milk to the egg mixture, quickly whisking to combine. This process helps prevent scrambling the eggs.
As you continue cooking the custard, bubble will start to form on the surface. Remove the saucepan from the heat and let it cool slightly. Add unsalted butter to the custard and whisk until combined. Pour the chilled custard directly onto plastic wrap in a prepared tray. Wrap the plastic wrap tightly around the custard to prevent any air bubbles from forming.
**Proofing the Dough**
To begin making the donuts, we need to proof the dough. Mix together flour, sugar, yeast, salt, and warm water in a large bowl until a shaggy dough forms. Cover the bowl with plastic wrap and let it rest for 30 minutes, allowing the yeast to activate.
After 30 minutes, the dough should have tripled in size, indicating that it is ready. Use your finger to test if the dough is ready by gently poking a hole into the dough. If the hole does not close immediately, the dough is not yet proofed enough. Gently dust some flour on top of the dough and press down with your fingers to release any air bubbles.
**Rolling Out the Dough**
Once the dough has proofed, it's time to roll it out. Divide the dough into six equal pieces using a kitchen scale or by weight. If one piece is heavier than the others, tear off some dough from the edge and attach it to the smaller piece. Use your palm to press down and deflate any air bubbles in the dough.
Gently pull down and tighten the dough from all sides to create tension on the outside. Form each piece into a ball with a smooth surface on top. If necessary, roll the dough around in your hand on a non-dusted surface as well. Tuck and pinch at the bottom of the dough, ensuring that the pinch is smooth.
**Dusting with Flour and Proofing**
Once all the dough pieces are ready, dust them with bread flour and gently press down to flatten the dough. Cover each dough piece with another baking sheet and proof until the dough doubles in size, about 40-50 minutes.
**Frying the Donuts**
To fry the donuts, heat oil in a heavy-bottomed pot or deep fryer to 340°F (175°C). When the dough balls have doubled in size, dust some bread flour on top of each one and gently press them down to flatten slightly. Carefully transfer two dough pieces into the hot oil at a time.
Fry the donuts until they are brown on the bottom about 1 minute, then flip them over to cook the other side for another minute. When both sides are nicely browned, use a chopstick or skewer to pop any air bubbles that have formed inside the dough. Remove the donuts from the oil with a slotted spoon and place them onto a wire rack.
**Assembling and Decorating**
Once the donuts have cooled slightly, insert a chopstick tip into the side of each donut to create space for the custard filling. Transfer chilled custard into a piping bag fitted with a decorating tip. Fold the top half of the piping bag over the custard and twist the bag to seal it.
Twist the piping bag one last time and set it aside. Roll the cooled donuts in powdered sugar to dust on all sides. Insert the piping bag into the side of each donut, wiggling the tip inside to create space for the custard filling. Pipe the chilled custard into each donut until they are plump and swollen.
Finally, pipe an extra dollop of custard at the opening to decorate the donuts. Your perfect donuts with chilled custard filling are now ready to be enjoyed!
