Piadina (Romagna Flatbread Made with Lard)

Variations

• Cassone (cascione): the same dough folded over a filling into a half moon and sealed before cooking — spinach and ricotta, or pumpkin. Closed from the start instead of folded at the end.
• Rimini against Forlì: the Rimini style is thinner and wider, the Forlì and Cesena style thicker and smaller. Two thicknesses live under one name.
• With olive oil: it makes the bread vegetarian and lighter in flavour. Olive oil is liquid at room temperature, though, so the dough is less crumbly and the cooked bread a little chewier — the tips below say why.
• Wholemeal (piadina integrale): raise the wholemeal share and add about 5% more water, or it will not roll.
• Not the same bread as focaccia: focaccia is yeasted, baked in an oven, and has its oil poured over the top. Piadina does not rise, cooks on a plate, and has its fat inside. Same country, opposite place for the fat.

Tips

• Gözleme has already drawn the distinction by where the fat goes, and this bread is the combination it leaves out. That page sets both cases out: "roti canai puts fat in the dough and cooks it in fat precisely so that it shatters", while gözleme itself keeps the pan dry "because it has to fold and be held in the hand". Piadina puts fat in the dough and not in the pan. That is why it folds and still breaks tenderly.
• What the lard does is shorten the gluten. Fat coating the flour particles leaves less surface for water to reach, so the gluten strands never link up far. Dough and gluten groups the doughs where you avoid gluten; this one uses ordinary wheat flour and lets the fat do that work. The bread tearing instead of stretching, and the dough not springing back under the pin, are the same fact twice.
• Which is why you knead it for five minutes. The instinct from yeasted bread runs backwards here: knead on and the gluten the lard pushed apart joins up again, the dough fights the pin, and the bread cooks tough.
• The half hour is not proving. There is no yeast, so there is nothing to prove. It is the rest gözleme describes — dough springing back "is a time problem, not a strength problem" — and 3mm only comes off a rested dough.
• If it balloons, that is a fault. A piadina that puffs has become a chapati, a bread whose whole point is separating into two layers. This one has to stay a single sheet or it tears at the fold, so prick the dome as it rises.
• A dry plate, and a hot one. Heat control reads a pan by the ripples in the oil, and there is no oil here; use a drop of water instead, which should skip at once. Cooked slowly on a low heat it dries right through and becomes a cracker.
• Swapping in olive oil changes the texture. Lard is solid at room temperature and stays in small pieces among the flour, which is what makes the crumbly layering. Oil spreads evenly and gives less of it. As cooking oils divides them, the fat here is a structural ingredient rather than a cooking medium.
• It stiffens as it cools, and that is the lard as well. Set fat goes firm again. Thirty seconds a side in a dry pan brings it back — reviving leftovers' dry-heat route.
