Choose a large frying pan and pour in enough oil to cover the bottom by 1 to 2 inches. Remember not to turn on the heat just yet! Dip a pair of kitchen shears into the oil to make sure the blades are coated.
Hold the piping bag in one hand and a pair of shears in the other over the frying pan. Begin squeezing the dough directly into the room-temperature oil, cutting it into 1-inch segments. Avoid mixing or disturbing the pieces at this stage.
After placing all the dough pieces in the oil, set the heat to medium-low. Once the oil starts bubbling around the edges of the bamieh, reduce the heat to low. The pieces will float after 8-10 minutes, indicating they're ready for gentle rotation to ensure even cooking and browning on both sides. Keep this process going for a total of 20-25 minutes.
Meanwhile, return the saucepan with the syrup to the burner and heat it briefly over low heat until it reaches a consistency similar to maple syrup.
Once the Bamieh pieces have turned a rich golden brown color, remove them from the oil using a slotted spoon or a spider strainer and transfer them to the saucepan with the syrup. Gently toss the pieces to coat them thoroughly with the syrup, and allow them to soak for about a minute.
Using a slotted spoon, transfer the Bamieh pieces onto a cooling rack or another strainer. Let any extra syrup drip off for a few minutes. Then, transfer the bamieh to a serving platter and sprinkle ground pistachios on top for garnish.
Store the Bamieh in an airtight container at room temperature.
