What are common mistakes when making You Tiao (油条) — Chinese Crullers: The Breakfast Tradition?

Question

Accepted Answer

Insufficient oil temperature: You tiao frying at 160-170C instead of 190-200C will not expand properly — they become dense, oily, and under-airy. Insufficient resting of the dough: A well-rested dough (especially after refrigeration) is much easier to stretch and handle.
