The Emilia-Romagna tradition of rolling egg pasta by hand with a mattarello (long rolling pin) on a wooden board. Two ingredients — flour and eggs — transformed by technique into the foundation of tortellini, tagliatelle, lasagne, and dozens of other shapes. The hand-rolling creates a rough, porous surface texture that grips sauce in a way machine-extruded pasta cannot. In Bologna, tradition says the sfoglia should be thin enough to see the Basilica of San Luca through it.
Standard ratio: 100g '00' flour per egg (about 55-60g egg). Knead 8-10 minutes until smooth and elastic — gluten development is essential. Rest 30-60 minutes wrapped tightly. Roll from centre outward, rotating frequently, on a wooden board — the wood's texture creates the micro-rough surface. For tagliatelle: roll to about 1mm. For tortellini: paper thin. For lasagne: slightly thicker. The wooden mattarello stretches rather than compresses the dough, creating different texture than a machine roller.
The cross-cut trick: score a cross on top of the dough ball before resting — it helps the gluten fibres relax evenly. If using a machine, stop at second-to-last setting for most pasta — paper-thin only for stuffed pasta. For silky texture, use half '00' flour and half semolina. Fresh pasta freezes perfectly — freeze on a tray then bag. Cook from frozen, adding 30 seconds.
Not kneading long enough — under-developed gluten makes brittle pasta. Dough too dry or too wet — it should feel like playdough, not bread dough. Not resting — gluten needs to relax. Rolling on a non-porous surface — marble or steel won't create the right texture. Flouring too heavily — excess flour makes gummy sauce. Cooking fresh pasta like dried pasta — fresh needs only 2-3 minutes.
