A Snack with a Shatteringly Crisp Shell

Brik — sometimes spelled brick, sometimes brik à l'œuf — is one of the great small pleasures of Tunisian home cooking. A paper-thin round of malsouka pastry, a spoonful of tuna and capers, a whole egg, a flick of harissa, and about ninety seconds in hot oil: that is more or less the entire recipe. What emerges is a golden, blistered parcel that cracks under your teeth and spills a soft yolk onto the plate. It is street food, Ramadan food, seaside food and quick-supper food all at once, and it belongs to a wider North African tradition of wrapping, folding and frying that runs from Tunis along the coast to Algiers and on into the Levant. The technique is not hard, but it is unforgiving. Moisture and lukewarm oil are the enemies; quick, confident hands are the cure.

Choosing and Handling the Pastry

Malsouka sheets — sold in North African grocers as feuilles de brik — are round, faintly translucent and thinner than filo. Fresh ones are supple and slightly tacky, which is exactly what you want, because they seal to themselves with a light press. Frozen versions are perfectly good: thaw them overnight in the fridge and keep them in their wrapper until the moment you begin.

If you cannot find malsouka, filo is the usual substitute. It is drier and more brittle, so use two sheets per brik, laid one over the other, and work with a gentler hand. Spring roll wrappers will also hold a filling, but the finished texture is chewier and less delicate — a different snack entirely.

• Keep unused sheets under a clean, barely damp tea towel; they crisp up in under a minute in open air.
• Work on a dry board, not a floured one — flour scorches in the fryer.
• Peel sheets one at a time, lifting from the edge rather than the centre.

Building the Filling

The classic filling is deliberately sparse. Too much and the parcel splits; too little and it collapses into a greasy crisp. For each brik you want roughly two tablespoons of solids and one egg.

• Good tinned tuna in olive oil, drained and flaked — about 60g per pastry.
• A teaspoon of capers, rinsed if salted, and a tablespoon of chopped flat-leaf parsley.
• One spring onion, finely sliced, or a little chopped shallot.
• A pinch of ground caraway or a small spoon of harissa, to taste.
• Salt and black pepper, lightly — the tuna and capers are already salty.

Some households add a slice of boiled potato, a few chopped olives, or a spoon of ricotta. All are welcome, but keep the mixture dry. If your tuna is watery, press it in a sieve first; wet filling steams the pastry from within and you will never get a crisp layer.

Folding and Sealing Without Leaks

Lay a sheet flat and place the tuna mixture in a short strip just below the centre, leaving a generous border all round. Make a small dip in the middle of the filling with the back of a spoon and slide the raw egg into it. Now fold the pastry over into a half-moon or a triangle, whichever the shape of your sheet suggests.

The sealing is where most briks fail. Press the air out gently from the fold outwards, then seal the open edge in stages: a thin smear of beaten egg white or a paste of flour and water along the rim, pressed firmly with your fingertips, then folded over once more into a narrow hem. A light crimp with the tines of a fork finishes the job. Do this immediately before frying — a sealed brik sitting on the board will weep and soften within minutes.

Frying for a Blistered, Dry Finish

Use a deep, heavy pan with about three centimetres of neutral oil — groundnut or sunflower — heated to around 175°C. A scrap of pastry should sizzle briskly and rise at once; if it browns in seconds, the oil is too hot and the egg will stay raw while the shell burns.

Slide the brik in seam-side down and hold it briefly with a slotted spoon so it sets in shape. Fry for sixty to ninety seconds on each side, spooning hot oil over the top as it cooks, which sets the upper layer without flipping too soon. Cook one or two at a time; crowding drops the temperature and gives you pale, oily pastry.

Drain on a wire rack rather than kitchen paper — paper traps steam underneath and softens the base you have just worked so hard to crisp.

To Serve, and What to Do When It Goes Wrong

Serve immediately with lemon wedges and a scatter of salt. Brik is eaten with the fingers, in bites, ideally standing up in the kitchen with the pan still hot. The yolk should be just liquid at the centre; if you prefer it firmer, choose a smaller egg or give it an extra twenty seconds.

If your layers turn out soggy, the culprit is almost always one of four things: oil below temperature, a leaking seal, an overfilled parcel, or filling that was too wet to begin with. Fix the oil first, then the seal, and you will find that brik becomes one of those dishes you make without thinking — a small, crisp piece of North Africa on a British weeknight plate.
