A shape defined by its irregularity
Every other shape in this collection has a target dimension. Maltagliati has only a range: shards between 15 and 25 mm, three-sided and four-sided mixed, cut at angles between 30 and 60 degrees. Within an hour of cooking they self-thicken the sauce because the shards break down at their thin points.
This is the reason maltagliati is paired with pulses in every region of Italy that makes it. The starch from the broken edges is what turns a thin chickpea broth into something that coats a spoon.
The 2 mm sheet is deliberate
At notch 5 the sheet is 2.0 mm — thicker than a tagliatelle and thinner than a pappardella. Thinner and the shards dissolve into the sauce; thicker and they stay chalky in the middle even after ten minutes.
Cut with a wheel or a knife, straight down and diagonally across the sheet in alternating directions, until the whole sheet is a pile of shards. Do not sort them. The mixture of sizes is the recipe.
Drying flat, not hung
Twenty millimetre shards cannot be hung; they slide off a dowel. Spread them on a cloth in a single layer for 8 hours instead, turning them once at the halfway point.
Partially dried maltagliati (4 hours) behaves quite differently from fully dried (8 hours): the partially dried ones thicken the sauce more because their edges break down faster. If you want a thicker result, cook them the same day.
Cooking with the chickpeas
Drop the maltagliati into the simmering chickpea sauce itself, not into a pot of water, with an extra 300 ml of water. Ten minutes, stirring twice so nothing catches on the bottom.
This is the one shape on the site that is cooked in its sauce. It works because maltagliati releases so much starch, and it means the sauce thickens to a stew-like consistency that a boiled-and-drained noodle could never produce.
