Put the dough in a bag with a “French star” nozzle with a diameter of 14 mm. My cooking lay overnight in the refrigerator. They say – this is how gluten is produced in the dough and it is prepared even better. I have little experience, I experimented, but it was really easier to breed them than unleavened dough.
I put it on a Teflon sheet, you can use siliconized parchment.
I have not tried to do this on a silicone mat.
But on a simple parchment, everything turned out sadly – the eclairs stuck, and the bottoms were concave.
