Georgia created this dish for MasterChef UK Professionals Season 18. Drawing on her personal connection to Spain — her parents lived there and she spent many holidays absorbing the food culture — Georgia built an elevated Spanish tapas plate around secreto iberico, one of the most prized pork cuts in Spanish gastronomy. She described it as 'Iberico pork with romesco, patatas bravas but without the brava sauce — I'm doing aioli instead, and crispy ham.' Jay Rayner called the romesco 'fantastic' and the pork cookery 'bang on.' Leyla Kazim exclaimed about the potatoes: 'Have you seen the crunch on that? I mean, that's just ridiculously good.' Marcus declared 'Absolutely love this dish. The romesco sauce is fabulous.' Monica said 'Georgia deserves to go through just on that bowl of potatoes.' Xanthe Clay's only niggle was that there was 'quite a lot of the romesco sauce.' This recipe addresses that with measured plating guidance while preserving every praised element.
Chef’s Notes: Addressing the Feedback
Romesco Quantity (Xanthe Clay’s Note)
The only critique of this otherwise triumphant dish was Xanthe’s observation that “there is quite a lot of the romesco sauce.” This recipe makes enough romesco for 4 generous servings, but the plating guidance calls for restraint: use a confident but not excessive spoonful as a base, letting the pork remain the star. Any leftover romesco is a gift - it keeps beautifully in the fridge for up to a week and is brilliant on grilled bread, with roasted vegetables, or stirred into pasta.
Romesco vs. Aioli: Avoiding the Clash
Marcus raised a valid concern before the cook: “Are these two big flavours going to be clashing on the plate?” The critics proved they don’t clash at all - the romesco is smoky, nutty, and acidic while the aioli is creamy and punchy with raw garlic. They complement each other beautifully when served in distinct zones: the romesco as a bed for the pork and peppers, the aioli as a companion for the crispy potatoes. Avoid mixing them together on the plate.
Sourcing Secreto Iberico
Secreto iberico is a specialty cut - the name means “secret” because it was traditionally a hidden cut that butchers kept for themselves. It comes from between the shoulder and loin of the Iberico pig, and its extraordinary marbling (comparable to wagyu beef) is what makes it so special. Look for it at specialist butchers, Spanish food importers, or online gourmet suppliers. If unavailable, Iberico pork pluma (from the loin end) or a well-marbled pork collar steak are the best substitutes, though neither quite matches the secreto’s unique texture.
The Potato Crunch
Monica said Georgia deserved to advance on the potatoes alone - that’s how good they were. The secret to that extraordinary crunch is threefold: par-boil until the edges are fluffy, shake vigorously to roughen the surfaces, and roast in a single layer in a properly hot oven with plenty of oil. Do not crowd the roasting tin -
use two trays if needed. Crispy rosemary leaves scattered throughout add aromatic crunch, and the crushed garlic cloves (skin on) perfume the oil as they roast.
Making Aioli by Hand
Traditional aioli is just garlic, olive oil, and salt - emulsified by patient pounding in a mortar. This recipe adds egg yolks and a touch of mustard for stability, making it far more forgiving for home cooks. The key is adding oil painfully slowly at first - literally drop by drop - until the emulsion catches. If it splits, start with a fresh yolk in a clean bowl and very slowly whisk the broken mixture into it. Using mild olive oil (not extra
virgin) as the base prevents bitterness; the good extra virgin goes in at the end for flavour.
Troubleshooting Guide
Pork is tough or dry: Secreto iberico cooks in minutes. It should be served medium (pink) at 135–145°F (57–63°C). Overcooking past medium will render the intramuscular fat out completely, leaving the meat dry and chewy. Use a thermometer and trust the timing.
Romesco is too smooth: Pulse rather than blend. A good romesco should have a coarse, rustic texture with visible pieces of nut and pepper, not a smooth puree.
Aioli splits: Oil was added too fast. Rescue by whisking a fresh egg yolk in a clean bowl, then very slowly drizzling the broken aioli into it while whisking constantly.
Potatoes aren’t crispy: Common causes: too crowded on the tray, not enough oil, oven not hot enough, or not par-boiled and roughened sufficiently. Ensure a single layer, generous oil, and 425°F (220°C).
Jamón won’t crisp: If sliced too thickly, it will stay chewy. Use the thinnest slices available, and bake until they darken slightly — they crisp as they cool.
Spring onions are limp, not charred: The pan or torch wasn’t hot enough. Blanch first, then dry thoroughly before charring. The surface must be dry for caramelisation to occur.
Storage & Make-Ahead Tips
• Romesco sauce: Make up to 3 days ahead. Store in an airtight container in the fridge. Bring to room temperature before serving — the flavours bloom as it warms.
• Aioli: Make up to 1 day ahead. Keep refrigerated. Best consumed within 48 hours due to raw egg yolks.
• Roasted peppers: Roast up to 2 days ahead. Store in olive oil in the fridge.
• Crispy jamón: Make day-of for best results. Can be crisped a few hours ahead and stored uncovered at room temperature.
• Potatoes: Par-boil up to 4 hours ahead and refrigerate on the roasting tray. Roast fresh just before serving — the crunch doesn’t survive reheating.
• Secreto iberico: Must be cooked and served fresh. Bring to room temperature for 30 minutes before cooking.
• Spring onions: Blanch ahead, char just before serving.
Variations & Substitutions
• Pork substitutes: If secreto iberico is unavailable, Iberico pluma, well-marbled pork collar steaks, or even a quality thick-cut pork chop will work. Adjust cooking times accordingly - thicker cuts need lower heat and longer cooking.
• Nut-free romesco: Replace almonds and hazelnuts with sunflower seeds or pepitas (pumpkin seeds). Toast until golden and proceed as normal.
• Quick aioli: For food safety or speed, use a whole egg (not just yolks) in a tall container and blend with an immersion blender, adding oil in a slow stream. Results in 60 seconds.
• Potato alternatives: Small roasted fingerlings or even thick-cut patatas bravas (cubed potatoes fried twice) can substitute.
• Georgia’s family-style version: True to her preferred serving style, this dish works brilliantly as a sharing platter - arrange everything on one large board or platter with the sauces in bowls for dipping.
• BBQ grill version: The secreto iberico is a natural for the outdoor grill. Sear over direct high heat, 2 minutes per side. Char the spring onions directly on the grill grates alongside.
Ingredients
Instructions
ROAST THE PEPPERS AND TOMATOES
Preheat the oven to 425°F (220°C). Place 5 red bell peppers (3 for romesco, 2 for the garnish), 2 halved tomatoes, and 2 whole unpeeled garlic cloves on a baking sheet. Drizzle with olive oil. Roast for 25–30 minutes, turning once, until the pepper skins are blistered and blackened in patches. Transfer the peppers to a bowl, cover tightly with cling film or a plate, and steam for 10 minutes. Peel, deseed, and separate: 3 peppers for the romesco, 2 for the garnish. Set the roasted tomatoes and garlic aside.
MAKE THE ROMESCO SAUCE
If using a dried nyora or ancho chile, soak it in hot water for 15 minutes, then drain and scrape out the flesh, discarding the skin. Toast the almonds and hazelnuts in a dry pan over medium heat until lightly golden, 3–4 minutes. In a food processor, combine the 3 roasted peppers, roasted tomatoes (skins removed), squeezed roasted garlic, toasted nuts, chile flesh or paprika, smoked pimentón, and sherry vinegar. Pulse to a coarse, textured sauce — not a smooth puree. With the motor running, drizzle in the olive oil. Season with salt. Use about 2–3 tablespoons per serving as a bed for the pork, rather than flooding the plate.
PAR-BOIL AND ROAST THE POTATOES
Place the halved or quartered potatoes in a large saucepan of well-salted cold water. Bring to a boil, then simmer for 8–10 minutes until just tender but not falling apart. Drain thoroughly and let steam dry for 2–3 minutes. Give the colander a firm shake to roughen the edges — these rough edges create the extraordinary crunch. Transfer to a roasting tin, toss with olive oil, crushed garlic cloves, rosemary leaves, and a generous pinch of salt. Spread in a single layer. Roast at 425°F (220°C) for 35–40 minutes, turning once halfway through, until deeply golden and shatteringly crispy.
MAKE THE CRISPY JAMÓN
Lay the jamón slices on a parchment-lined baking sheet in a single layer. Bake at 375°F (190°C) for 8–10 minutes until crisp and wavy. Cool completely — they will crisp further as they cool. Break into shards or leave as whole crisp slices.
MAKE THE GARLIC AIOLI
In a medium bowl, whisk together the egg yolks, grated garlic, lemon juice, Dijon mustard, and a pinch of salt until combined. Very slowly, drop by drop at first, begin adding the mild olive oil while whisking constantly. As the emulsion takes hold and thickens, you can increase to a thin, steady stream. Once all the mild oil is incorporated, whisk in the extra virgin olive oil for finishing flavour. Season with salt, white pepper, and additional lemon juice to taste. The aioli should be thick, glossy, and punchy with garlic. Cover and refrigerate until needed.
PREPARE THE CHARRED SPRING ONIONS
Bring a saucepan of salted water to the boil. Blanch the trimmed spring onions for 60–90 seconds until just wilted but still vibrant green. Drain and pat dry. Toss lightly with olive oil and a pinch of salt. Using a kitchen torch, char the spring onions until blistered and lightly blackened in patches, turning to char evenly. Alternatively, cook in a smoking-hot dry griddle pan for 1–2 minutes per side.
DRESS THE ROASTED RED PEPPERS
Tear or slice the 2 reserved roasted red peppers into wide strips. Toss gently with extra virgin olive oil, sherry vinegar, and a pinch of salt.
COOK THE SECRETO IBERICO
Remove the secreto from the refrigerator 30 minutes before cooking to bring to room temperature. Pat thoroughly dry with paper towels. Season generously with flaky salt and cracked black pepper on both sides. Heat a cast-iron skillet or heavy griddle over high heat until smoking. Add a thin film of olive oil. Lay the secreto flat in the pan — it should sizzle aggressively on contact. Sear for 2–3 minutes per side without moving, until a deep golden crust develops. The internal temperature should reach 135–140°F (57–60°C) for medium, which is optimal for this cut. Secreto iberico is thin and heavily marbled — it cooks very quickly. Transfer to a warm plate, tent loosely with foil, and rest for 5 minutes. Slice thinly against the grain.
ASSEMBLE AND SERVE
Spoon a measured bed of romesco sauce (2–3 tablespoons) slightly off-centre on each warm plate. Arrange the dressed roasted red pepper strips alongside. Fan sliced secreto iberico over the romesco. Nestle the charred spring onions beside the pork. In a separate bowl or on the same plate, mound the crispy rosemary potatoes. Dollop garlic aioli over the potatoes. Crown the potatoes with shards of crispy jamón. Finish with a drizzle of your best extra virgin olive oil and serve immediately.
