Steeping saffron into the dough water
Crush 0.3 g of threads between your fingers into a cup, add 60 ml of water at 60 °C, and leave 20 minutes. The water should be deep orange-gold before it goes anywhere near the flour; if it is pale yellow, the saffron is old and the batch will be colourless.
Use that 60 ml plus 120 ml of plain water to reach the 180 g total. Adding the saffron directly to the flour instead leaves uneven orange streaks that dry into dark speckles.
A 14 mm rope is the target
Malloreddus are bigger than cavatelli: a 14 mm rope cut into 12 mm beads, then dragged across a ridged board — the traditional ciuliri, or any board with 4 mm grooves — with the thumb, finishing with a firm press that curls the shell.
The groove pattern is what makes the shape. A malloreddus with no ridges is just a thick bead, and it will not hold a sauce the way a ridged one does.
Thirty-six hours of drying
Malloreddus are the thickest dry shape here — 14 mm across — and they take 36 hours to dry through. Anything less and the centre stays damp; the shell looks dry while the core is still soft, and they go mouldy in the bag within ten days.
Test at 36 hours by breaking one in half. The cross-section must be uniform in colour all the way through, with no darker ring at the centre.
Cooking and the double-saffron trick
Nine minutes at a rolling boil. A 14 mm dried shell is genuinely dense, and undercooked malloreddus are unpleasant in a way that undercooked thin pasta is not.
Add a second, tiny pinch of saffron to the sauce at the end, off the heat. The saffron in the dough has been cooked for thirty-six hours of drying plus nine minutes of boiling and has lost most of its top notes; the fresh pinch puts them back.
