Navajas gratinadas are Galician, from the rías where razor clams live in clean sand and come to the table in their own long shells. What makes them this dish, and not a neighbour's baked clam, is the light hand: the navaja is opened a la plancha, spooned with a small cover of jamón, mild Galician cheese, and crumbs, then browned before the meat has time to toughen.

The method that decides it is the heat. Razor clams are tender for a short minute and stubborn after that, so I open them on a very hot pan, save the briny liquor, and let the broiler do only the browning. The topping should sit like a thin crust, damp with clam juice and olive oil, not like a blanket. You want crisp crumbs, a little jamón salt, and the sweet sea taste still first.

Far from Galicia, buy live Atlantic razor clams if you can. If not, use zamburiñas or small scallops on the half shell; they are sweeter and less briny, so use a lighter hand with the cheese and give them a minute less under the grill. No canned clam here; it gives you salt and water, not navajas. In the Margin beside this one I wrote, do not bury the clam. Siempre sale, si lo sigues.

Navajas belong to the sandy banks of Galicia's rias, especially the Atlantic inlets where shellfish gatherers work by tide and the market changes with the water. The common Galician treatment is a la plancha with garlic, parsley, oil, and lemon, because the flesh is thin and sweet and punishes delay. Gratinadas are the feast-table cousin: jamón, breadcrumbs, and a mild cow's-milk cheese give a browned cover while the clam stays the reason for the dish.

Equipment Needed

  • Heavy plancha or wide frying pan with lid
  • Fine sieve or coffee filter
  • Small frying pan
  • Rimmed baking tray
  • Coarse salt or crumpled foil to steady the shells

Instructions

  1. 1

    Purge the sand

    Dissolve 35g sea salt in 1L cold water in a tall bowl. Stand the razor clams upright, the way they sat in the sand, and chill them for 1 hour, or up to 2 hours if they came very sandy. Lift them out of the water, leaving the grit behind, and rinse under cold running water. A live navaja smells clean and closes or tightens when touched; if one smells sour or stays gaping, throw it away.

    Do not purge shellfish in unsalted tap water. It kills them and leaves you with dead clams before the pan is even hot.
  2. 2

    Open on the plancha

    Set a heavy plancha or wide frying pan over high heat until a drop of water skates and vanishes. Add the clams in one layer, cover, and cook 60 to 90 seconds, lifting each one out as it opens. Work in batches so they do not stew in their own liquor. Tip any juices from the pan into a cup; that is the taste of the ria, and it goes back into the topping.

  3. 3

    Set the shells

    When cool enough to handle, remove the empty top shell from each clam and keep the deeper shell. Loosen the meat, trim away any gritty dark sand pocket if you see one, cut long clams into 2 or 3 bite-size pieces, and put the meat back in its shell. Strain the collected clam liquor through a fine sieve or coffee filter; stop before the last gritty spoonful.

  4. 4

    Cook the sofrito

    Warm 30ml olive oil in a small pan over low heat. Add the onion and cook 8 to 10 minutes, stirring often, until soft, sweet, and pale gold; this little sofrito, the slow onion base, gives the crumbs body without stealing the shellfish. Add the garlic for 1 minute, then the jamón for 30 seconds. Pour in the wine and 60ml strained clam liquor and simmer until only a glossy few spoonfuls remain.

  5. 5

    Mix the crumbs

    Take the pan off the heat. Stir in the breadcrumbs, cheese, parsley, pepper, and remaining 15ml olive oil. The mixture should be loose and damp, not dry. If it clumps heavily, add 1 teaspoon more clam liquor; if it runs, add 1 teaspoon breadcrumbs. Pésalo, no lo adivines, then adjust by the spoon, not by panic.

  6. 6

    Top the clams

    Heat the broiler, the top grill of the oven, to high and set a rack about 10cm below it. Arrange the shells on a rimmed tray, braced on coarse salt or crumpled foil so they do not tip. Spoon about 1 heaped teaspoon, roughly 6g, of topping over each clam. Keep a little of the meat visible at the edges; if all you can see is bread and cheese, you've hidden the reason you bought navajas.

  7. 7

    Brown fast

    Slide the tray under the broiler for 2 to 3 minutes, watching the whole time, until the crumbs are golden in spots and the cheese has just melted. The clam meat should look opaque and glossy, not curled tight. Serve at once with lemon wedges, and let each person add a squeeze if they want it. Siempre sale, si lo sigues.

Chef Tips

  • Buy navajas the day you cook them, from a fishmonger with good turnover. They should smell clean, close when touched, and feel heavy for their size. Sourcing wins here; no method rescues tired shellfish.
  • If you cannot find razor clams, use zamburiñas or small scallops on the half shell. They are sweeter and thicker, so cut the broiler time to about 2 minutes and keep the topping thinner.
  • Use San Simón da Costa if you can, because its gentle smoke suits the jamón without shouting over the clam. Arzúa-Ulloa or Tetilla works too. A sharp cheese makes the shellfish taste smaller, and that is not the point.
  • Do not pile the topping high. A teaspoon per shell is enough. More than that turns a Galician razor clam into a breaded ham bite, which is a different thing and not as good.
  • Serve these straight from the broiler with a cold glass of Albariño or Ribeiro. Leftovers are not worth saving; shellfish under crumbs turns tough when reheated.

Advance Preparation

  • The onion, garlic, jamón, wine, and clam liquor base can be cooked up to 24 hours ahead, cooled, and refrigerated. Stir in the breadcrumbs, cheese, parsley, and olive oil just before topping the clams.
  • Purge the clams 1 to 2 hours before cooking. Do not leave them overnight in salted water; they are living shellfish, not beans.
  • Open, top, and gratinate close to serving. Once the clams are cooked, they should go to the table at once.
