Bacalhau com natas
Shredded salt cod baked in béchamel and cream with onion and potato — the richest and most comforting of all bacalhau preparations, closer to a gratin than a fish dish. It appears on the Sunday lunch menus of Portuguese restaurants from Braga to Faro, and its relationship to à brás and à Gomes de Sá demonstrates how far bacalhau can travel texturally through technique while remaining recognisably the same fish. Bacalhau com natas requires a thickened béchamel (bechamel densa), a good ratio of cod to potato, and confidence with cream — this is not a restrained dish. The surface must be properly gratinéed: golden brown with spots of deep colour where the cream has caramelised.

The Method
1
Warm the olive oil in a wide pan over a medium flame. Add the sliced onions and cook, stirring occasionally, until completely soft and pale gold — they must not colour deeply. The test: a piece pressed between finger and thumb offers no resistance.
2
Make the béchamel densa. Melt the butter in a heavy saucepan, add the flour, and stir constantly over a medium heat for 2 minutes. Add the warmed milk in a steady stream, whisking without pause, then pour in the cream. Continue to cook, stirring, until the sauce is thick enough to hold a clear channel when a spoon is drawn across the base of the pan. Season conservatively — the bacalhau carries residual salt. Grate in the nutmeg. If using, remove the pan from the heat and stir in the egg yolks before they can scramble.
3
Fry the sliced potatoes in olive oil until cooked through and lightly golden at the edges. Drain on a rack. The test: a slice bends without breaking but does not crumble.
4
In a large bowl, combine the shredded bacalhau, softened onion, fried potato slices, and roughly two-thirds of the béchamel. Fold together so that every element is evenly coated. Transfer the mixture to an earthenware gratin dish. Spread the remaining béchamel in an even layer over the surface.
5
Bake at 220 °C for 20–25 minutes. This is where the dish lives or dies: the surface must achieve a deep, uneven golden-brown, with darker spots where the cream has caramelised at the edges. A pale or uniformly cream surface means the heat was insufficient or the time too short. The smell shifts from milky to toasted and savoury; the dish bubbles at the rim.
III
Quality Hierarchy
01
Reserve — Wild-caught, thick-loin bacalhau desalted over 48 hours with multiple water changes; estate-pressed single-quinta olive oil; full-fat unhomogenised milk; egg yolks stirred into the béchamel.
02
Estate — Good Portuguese or Norwegian bacalhau from a reliable fishmonger; a named Dão or Alentejo olive oil; the egg-yolk enrichment included.
03
Market — Supermarket salt cod of reasonable thickness, properly desalted; a decent olive oil; the egg yolks omitted without serious loss.
04
House — Pre-desalted bacalhau from a chilled packet; any mild olive oil; the dish remains wholly recognisable and honest at this level.

Sensory Tests
◇Touch. Onion slices press to nothing between finger and thumb — no fibrous resistance remains.
◇Sight. Béchamel holds a clean channel across the pan base when a spoon is drawn through it — thick, not pourable.
◇Touch. Fried potato slices bend without snapping and without crumbling to mush.
◇Smell. The baking dish gives off a toasted, savoury aroma distinct from the earlier milky smell, and the edges bubble visibly.
◇Sight. Surface colour is deep golden-brown with darker caramelised spots — no pale cream remains on top.
◇Where it lives or dies. The surface must be deeply gratinéed — golden brown with caramelised spots — not pale or uniformly cream; an under-gratinéed top is an unfinished dish.
