Minho and Douro, Portugal
A northern Portuguese preparation of bacalhau — desalted salt cod roasted in the oven with a crust of crumbled cornbread (broa), olive oil, garlic, and parsley. The cornbread crust absorbs the olive oil during roasting and forms a thick, golden-brown mantle over the fish that simultaneously protects the delicate cod and provides textural contrast — the crust is almost sand-like in texture, slightly crisp at the surface and moist where it contacts the fish. This preparation demonstrates how the broa (Minho and Douro cornbread, made from maize flour, dense and slightly sour) transforms bacalhau through the introduction of a completely different flavour — the corn's natural sweetness against the salt-cured fish.
The broa must be day-old or older and crumbled, not processed — rough, irregular crumbs produce the right texture. Mix the crumbled broa with olive oil, garlic, parsley, and salt. Pat the thick-cut, skin-on bacalhau dry. Coat the top surface (flesh side up) generously with the broa mixture. Roast at 200°C for 20-25 minutes until the crust is deep golden. Serve with boiled potatoes and greens.
Broa is available from Portuguese bakeries and delis — it keeps for 3-4 days and only improves as it dries for this preparation. Any dense cornbread (not American-style sweet cornbread) can substitute in a pinch. The broa crust technique can be applied to other fish — monkfish (tamboril) is particularly good this way. Pair with white Douro or Vinho Verde.
Using fresh broa — too wet, doesn't crisp. Making the crumbs too fine — produces a flat crust. Insufficient olive oil in the crumb mixture — the crust won't bind. Not drying the fish surface before coating — the broa mixture slides off.
