What are the causes of faults in rough puff pastry?

Faults in rough puff pastry can arise from several factors, including improper mixing techniques, which can lead to uneven layers, and inadequate chilling, which prevents the fat from remaining solid and results in a greasy texture. Overworking the dough can also develop too much gluten, causing toughness instead of flakiness. Additionally, using the wrong type of flour or incorrect oven temperatures can affect the pastry's rise and texture. Proper technique and attention to temperature are crucial for achieving the desired flaky layers.
