Crispy shaobing stuffed with you tiao creates a satisfying textural contrast for breakfast. A classic family combination that's a beloved Chinese morning tradition.
In a large bowl, combine all-purpose flour, sugar, and salt. Dissolve yeast in warm water and add to the flour mixture. Mix until a rough dough forms.
Knead the dough for 8–10 minutes until smooth and elastic. Cover with a damp cloth, and let rise in a warm place for about 60 minutes or until doubled in size.
Preheat oven to 425°F. Punch down dough and divide into 4 equal pieces. Roll each piece into an oval about 1/4 inch thick, brush with vegetable oil, and sprinkle generously with sesame seeds. Gently press the seeds in.
Place the shaobing ovals sesame-side up on a baking sheet. Bake for 15–18 minutes until golden brown and crisp, watching closely to prevent over-browning.
Slice each shaobing open lengthwise, and stuff with half a you tiao per portion. Serve immediately while the shaobing is still warm and crisp.
