Sift the bread flour and set aside. In a saucepan, combine butter chunks, water, milk, salt, and sugar. Heat over medium until simmering but not boiling.
02 -
Remove saucepan from heat, add flour all at once, and vigorously mix with a rubber spatula until a smooth ball forms with no visible flour.
03 -
Return saucepan to medium heat and cook for 3-5 minutes, stirring constantly until water evaporates and a thin skin forms on the bottom of the pan.
04 -
Transfer dough to stand mixer with paddle attachment. Mix on low speed for 1 minute to cool slightly. Gradually add lightly whisked eggs in small increments, allowing each addition to fully incorporate before adding more.
05 -
The dough is ready when it slowly falls from the paddle in a V shape. It should be glossy and pipeable but not runny. The exact egg quantity may vary based on moisture evaporation and flour type.
06 -
Transfer dough to a pastry bag fitted with a French star nozzle (1.3 cm diameter). Refrigerate dough for 1 hour to stabilize.
07 -
Pipe 14 equal-sized eclairs onto a perforated baking mat or parchment-lined baking sheet, leaving space between each for expansion. Pipe at a 45° angle with even pressure. Gently tap the tips with a lightly wet finger to smooth and seal ends.
08 -
Lightly dust the piped dough with powdered sugar to prevent cracking. Freeze for at least one hour.
09 -
Preheat oven to 200°C (no fan). Place frozen eclairs in oven, reduce temperature to 170°C (no fan), and bake for 40 minutes. Avoid opening the oven door during the first 30 minutes. Eclairs should be golden, well-puffed, and have a mostly dry interior.
10 -
Allow eclairs to cool completely on the baking mat to room temperature before filling and glazing.
11 -
Whisk sugar and egg yolks in a bowl for 1-2 minutes until fluffy. Add cornstarch, flour, and vanilla, mixing until smooth.
12 -
Heat milk until just simmering. Slowly pour into egg mixture while whisking to temper the yolks. Return mixture to saucepan and cook over medium heat, stirring constantly until thickened (about 1 minute after boiling).
13 -
Remove from heat and gradually incorporate softened butter chunks until fully combined. Strain if necessary. Transfer to a shallow bowl and cover surface directly with plastic wrap to prevent skin formation. Cool completely before using.
14 -
Semi-melt chocolate in microwave. Heat cream in a saucepan until just simmering. Pour hot cream over chocolate and stir until smooth. Mix in butter until fully incorporated.
15 -
Allow ganache to cool to approximately 30°C. It should have a smooth, spreadable consistency—neither too runny nor too thick.
16 -
Create three small holes in the bottom of each eclair using a skewer or piping nozzle, or insert a nozzle into the side. Gently pipe pastry cream into each eclair until fully filled.
17 -
Dip the tops of filled eclairs into the cooled chocolate ganache for an even coating. Gently tap to remove excess glaze or use fingers to clean edges for a professional finish.
18 -
Allow glaze to set for 2-3 minutes in the refrigerator for a glossy finish. Serve immediately for optimal texture and flavor. Store any leftovers refrigerated for up to one day.
