Lahmacun

Preparation

1. For tomato sauce:

   Step 1

   Heat oil in a large skillet over medium-high heat. Add onion, garlic, and serrano chile and cook, stirring often, until beginning to brown, about 4 minutes. Add tomatoes, breaking them up with your hands, piquillo peppers, brown sugar, vinegar, and cumin; season with salt and pepper. Bring to a boil, reduce heat, and simmer, stirring often and mashing with a potato masher (or a spoon), until thickened, 15–20 minutes. Let cool slightly, then purée in a blender until smooth; season with salt and pepper to taste.

2. For meat:

   Step 2

   Heat butter in a large skillet over medium-high heat until golden brown, about 3 minutes. Add onion and garlic and cook, stirring often, until softened, 5–8 minutes. Add lamb, beef, Aleppo pepper, ras-el-hanout, and cumin; season with salt and pepper. Cook, breaking up with a spoon, until browned, 6–8 minutes. Transfer to a plate and let cool.

3. For assembly:

   Step 3

   Place a rack in lower third of oven and preheat to 500°F. Cut dough into 4 pieces. Working with 1 piece at a time and keeping remaining pieces covered, gently stretch dough into 12" rounds and transfer to parchment-lined baking sheets. (If dough springs back, let rest 10 minutes, then stretch again, resting as needed, until dough is thin).

   Step 4

   Spread each round of dough with a layer of tomato sauce; season with salt and pepper and top with a thin layer of meat mixture. Working in batches, cook lahmacun until crusts are browned and crisp, 10–12 minutes.

   Step 5

   Toss parsley and lemon juice in a small bowl. Top each lahmacun with parsley mixture and drizzle with oil.

   Step 6

   DO AHEAD: Sauce and meat mixture can be made 1 day ahead. Cover separately and keep chilled.
