Frango com Alheira Gratinado

Chicken

• 720 g chicken breasts, 4 breasts of ~180g, butterflied to an even ~1.5cm
• fine salt, with restraint — the alheira, cheese and sun-dried tomato all bring salt, to taste
• black pepper, freshly ground, to taste
• 30 ml olive oil, cooking grade for searing, or HOLL rapeseed oil

Rendered alheira paste

• 300 g alheira, 2 sausages, casing removed, filling crumbled — a Mirandela, Vinhais, Barroso-Montalegre or game (de caça) alheira if you can find one
• 15 ml olive oil
• 60 ml dry white wine
• 60 ml lactose-free double cream, binds exactly like standard cream, but reads slightly sweeter

Gratin topping

• 150 g low-moisture mozzarella, grated or thinly sliced — not fresh ovoline, which weeps
• 60 g oil-packed sun-dried tomatoes, drained and sliced
• 30 g Sbrinz AOP, finely grated, as an aged-cheese layer under the mozzarella(optional)
• 30 g panko, tossed in 1 tbsp of the amber alheira oil for a croquette-like crust(optional)

Bay-scented rice

• 300 g rice, basmati or Carolino
• 1 bay leaf
• salt, for the cooking water, to taste

Tomato, onion and coriander salad

• 2 ripe tomatoes, quartered and sliced
• ½ red onion, thinly sliced
• 15 g fresh coriander, a small handful, chopped
• 30 ml extra-virgin olive oil
• 15 ml balsamic vinegar
• 5 ml red wine vinegar, or lemon juice — the sharp acid the plate needs
• salt, a pinch on the onion, the rest to finish, to taste

Mise en place

1. 1

   Pat the 4 chicken breasts (720 g) dry and butterfly each one: hand flat on top, knife parallel to the board, cut through the thick side to within ~1cm of the far edge, then open it like a book. Aim for an even ~1.5cm thickness.

   8m

   The goal is uniform thickness, not thinness. A whole breast is a wedge, and by the time the thick end is done the thin tail is chalk. Even thickness means the whole piece reaches temperature together, and it gives the topping a flat surface to sit and gratinate on.

2. 2

   Season both sides lightly with fine salt and black pepper and leave the breasts out at room temperature while you build the paste.

   1m

   Tip: Cold-from-the-fridge meat cooks unevenly. Twenty minutes on the counter takes the chill off the centre. Go easy on the salt: three salty components are still to come.

3. 3

   Slit the casings of the 2 alheiras (300 g) lengthwise, peel them away and crumble the filling. Drain and slice the 60 g sun-dried tomatoes. Grate the 150 g mozzarella, and the 30 g Sbrinz if using. Preheat the oven to 200°C fan.

Start the rice

1. 4

   Cook the 300 g rice in salted water with 1 bay leaf, by your usual method. It wants about 15 minutes and can then sit covered off the heat until the chicken is ready.

   15m

   Tip: The bay leaf is the whole intervention. It stops the rice being a blank slab under a big-flavoured main.

Render the alheira paste

1. 5

   Warm the 15 ml olive oil in a wide frying pan over medium-high heat and add the crumbled alheira. Break it up, then let it sit against the hot pan in patches, stirring only every 30–60 seconds, for 4–6 minutes, until it stops looking like wet paste, catches brown edges, and the oil around it turns amber and smells of toasted garlic and paprika.

   6mmedium-highwide frying pan

   The filling is already cooked, so this is not about safety. It is about browning: Maillard reactions on the meat and the bread are where the smoke-garlic-paprika depth lives. Crumbled in raw and creamed, the sausage stays pale, gummy and one-note, the same dull result you get from microwaving an alheira. Do not stir constantly and do not crowd the pan, or it steams grey instead of colouring.

   Tip: If you are doing the panko crust or the rice finish, spoon off 1 tbsp of the amber oil now, before the wine goes in.

2. 6

   Deglaze with the 60 ml dry white wine, scraping up the fond, and let it cook down for about a minute until the pan is nearly dry again.

   Tip: This is the vinho branco step from the traditional Portuguese oven versions. It buys acid and depth that the cream alone cannot, on a plate that is otherwise short of acid.

3. 7

   Take the pan off the heat and stir in the 60 ml lactose-free double cream to bind it into a thick, spreadable paste. Taste and correct with a pinch of salt and a grind of pepper.

   1moff the heat

   Cream goes in off the heat so it does not catch or break. Lactose-free cream reads slightly sweeter because the lactose is already split into glucose and galactose; correct with salt, not more paprika. The alheira already carries plenty of garlic and paprika and extra spice muddies it. The paste should mound on a spoon and sit on the chicken without running; if it is loose, give it another minute back on the heat.

Sear and assemble

1. 8

   Wipe the pan, add the 30 ml olive oil and get it hot. Sear the breasts about 1.5 minutes per side, then move them to an oven tray, cut-side up.

   4mhighoven tray

   Colour on the outside only. The breasts finish in the oven; cooking them through now is the express route to dry chicken. Beyond 4 breasts, sear in batches so the pan does not drop temperature and poach them.

2. 9

   Blanket each breast with the alheira paste. Scatter the 30 g Sbrinz over the paste if using, then top with the 150 g mozzarella and the 60 g sliced sun-dried tomatoes. If doing the crust, toss the 30 g panko with the reserved tablespoon of alheira oil and press it over the top.

   3m

   Low-moisture mozzarella is deliberate. Fresh mozzarella weeps water as it heats; the water pools on the paste, dilutes it, cools the surface and stops it browning. If fresh is all you have, slice it and blot it hard between paper, and accept a wetter top.

   Tip: The Sbrinz layer adds aged-cheese umami under the melter. The panko gives back some of the crunch a fried alheira is prized for, and which a creamed paste otherwise throws away.

Bake, grill, rest

1. 10

   Bake at 200°C fan for 10–12 minutes, until the thickest part of a breast reads 63–64°C on a probe.

   12m200°C fanprobe thermometer

   Pull on temperature, not on the look of the cheese. Cheese browning and breast doneness run on different clocks, and the breast loses: past ~65°C the fibres contract and squeeze out their water. 74°C is an instantaneous kill temperature; the same pasteurisation is reached at lower temperatures held for time. At 63–64°C, then held under a hot cheese blanket while it rests, the breast is safe and far juicier than one driven to 74°C. Colour and clear juices are unreliable cues in chicken; use a probe.

   Switch to the grill on high, rack near the top, for 2–3 minutes to blister and gold the cheese fast without cooking the chicken further. Stay at the oven.

   With lactose-free cream in the paste, the surface sugars catch a shade sooner than you expect. The line between golden and burnt is seconds. The moment you smell toasted cheese, you are nearly there.

   Rest the tray for 5 minutes before serving.

   Tip: Carryover takes the breast to ~67–68°C under the molten cheese and keeps it in the pasteurising band for minutes. The top also sets so it cuts cleanly.

Salad and rice

1. 13

   While the chicken bakes, slice the ½ red onion thinly, toss it with a pinch of salt and leave it 5 minutes. Quarter and slice the 2 tomatoes and chop the 15 g coriander.

   5m

   Tip: The salt draws out some of the onion's juice and knocks back its harsh raw bite.

2. 14

   Whisk the 30 ml extra-virgin olive oil with the 15 ml balsamic and 5 ml red wine vinegar (or lemon). At the last moment, toss the tomato, onion and coriander with the dressing and salt to taste.

   2m

   Balsamic alone is sweet, and the plate is already rich and faintly sweet from the cream, the sun-dried tomato and the lactose-free dairy. The sharp vinegar is what cuts through the alheira, cheese and cream. Dress last so the onion does not weep and the salad stays live.

3. 15

   Fluff the rice and lift out the bay leaf. If you reserved alheira oil and did not use it all on the panko, stir a spoonful through.

   1m

   Tip: The alheira oil through the rice is optional and very good.
