Creating the perfect crust is essential for Chinese Egg Tarts. Prepare a buttery and flaky pastry by combining flour, butter, sugar, and a touch of salt. Knead the dough until it comes together, then roll it out and cut into individual tart shells. The key is to handle the dough gently and avoid overworking it, ensuring a tender and melt-in-your-mouth crust that complements the luscious filling.
