Venice, Veneto
Venice's canonical Ash Wednesday and Good Friday pasta: bigoli (thick, rough-extruded whole-wheat spaghetti) dressed with a sauce of slowly dissolved salt-packed anchovies and onions — the onions cooked for 30-40 minutes in olive oil until completely collapsed and sweet, the anchovies added late and dissolved into the oil-onion base to create a savoury, umami-rich, harmonious sauce with no visual trace of anchovy remaining. A fasting pasta that is simultaneously poor-kitchen-simple and extraordinarily complex in flavour.
Sweet, long-cooked onion and dissolved anchovy salt — invisible umami sauce that coats every rough surface of the bigoli, simple and profound simultaneously
The onions must be cooked very slowly (30-40 minutes at absolute minimum) until they are completely soft, sweet, and collapsed — any remaining texture or sharpness means insufficient cooking. The salt-packed anchovies (not oil-packed) must be rinsed and de-spined before being added — salt-packed have more concentrated flavour. The anchovies are added to the cooked onions and stirred over gentle heat until they literally dissolve and disappear into the sauce. No other seasoning is added — the anchovies provide all the salt.
The sauce can be made in large batches (it keeps for 3 days in the refrigerator) and bigoli is added fresh each serving. Bigoli must be bought from a specialist — the rough-extruded texture (through a bronze die, not Teflon) is what grips the oily, invisible sauce. If bigoli is unavailable, thick spaghetti alla chitarra is the best substitute. Do not add cheese — a fish pasta takes no dairy.
Under-cooking the onions — they must be completely sweet and soft, with no residual sharpness. Using oil-packed anchovies instead of salt-packed — the flavour is less concentrated. Adding garlic — traditional bigoli in salsa is specifically garlic-free, which distinguishes it from all other anchovy pasta. Over-salting — the anchovies are the only salt needed.
