The essence of Catalan cuisine in one deeply Mediterranean sauce

Romesco sauce is one of the great treasures of Catalan gastronomy. Originating in the Tarragona area and deeply connected with the maritime traditions of the Catalan coast, it has become an essential accompaniment to calçots, fish, seafood, meat and roasted vegetables.

Its character comes from an extraordinary combination of simple ingredients: almonds, hazelnuts, tomatoes, garlic, ñora pepper, bread, olive oil and vinegar, together with a touch of bitxo or chilli for gentle heat.

The tradition is closely linked to popular and coastal cooking. Romesco developed as a versatile sauce that could accompany a wide variety of ingredients while making use of products commonly found in Catalan kitchens.

Its texture can range from rustic and chunky to smooth and creamy, depending on the local tradition, the family recipe and the dish it is intended to accompany.

When served with calçots, it becomes part of the famous Catalan calçotada tradition, although not every calçot sauce is exactly the same as traditional romesco.

Its beauty lies in the balance:

sweet tomato + toasted nuts + roasted garlic + acidity from the vinegar + aromatic ñora + gentle chilli heat.

Premium Traditional Romesco Sauce

Makes approximately 4–6 servings

Ingredients

• 2 large ripe tomatoes
• 1 whole head of garlic
• 50 g toasted almonds
• 50 g toasted hazelnuts
• 2 dried ñora peppers
• 1 slice rustic bread
• 100–120 ml extra virgin olive oil
• 1–2 tablespoons wine vinegar
• 1 small bitxo or chilli, to taste
• Salt
• Freshly ground black pepper, optional

Step-by-Step Preparation

01 · Prepare the Ñora Peppers

The aromatic heart of Romesco

Cut the ñoras open and remove the seeds.

Place them in warm water for approximately 30–60 minutes, until the flesh softens.

Once hydrated, scrape out the flesh with a spoon or small knife.

Set aside.

02 · Roast the Tomatoes and Garlic

Let the fire create the flavour

Preheat the oven to 200°C / 392°F.

Place the tomatoes and whole head of garlic on a baking tray.

Roast for approximately 25–35 minutes, until the tomatoes are tender and lightly charred and the garlic becomes soft and creamy.

The roasted garlic adds sweetness and depth to the sauce.

03 · Fry the Bread

Heat a small amount of olive oil in a frying pan.

Fry the slice of bread until golden and crisp.

Remove and drain.

The bread provides body and helps create Romesco’s characteristic texture.

04 · Toast the Nuts

If the almonds and hazelnuts are not already toasted, lightly toast them in a dry frying pan.

Watch carefully so they do not burn.

Toasting intensifies their flavour and aroma.

05 · Build the Base

Place the following ingredients in a mortar:

almonds + hazelnuts + fried bread + ñora + roasted garlic.

Crush slowly until you obtain a rustic, aromatic paste.

A little roasted tomato can be added to make the process easier.

06 · Add the Tomatoes

Peel the roasted tomatoes and add them to the mortar.

Work the mixture until the ingredients are well combined.

There is no need to make it completely smooth.

Traditional Romesco can retain small pieces of nuts, adding character and texture.

07 · Add the Oil and Vinegar

Finding the final balance

Gradually incorporate the extra virgin olive oil, continuing to work the mixture.

Add the vinegar little by little.

Taste.

Adjust the salt.

Then adjust the acidity according to your preference.

08 · Add the Bitxo

Add a small amount of bitxo or chilli.

The quantity depends entirely on how spicy you want the sauce.

The heat should provide character without overpowering the tomato, nuts and ñora.

The Perfect Texture

Romesco can be prepared traditionally in a mortar for a rustic texture, or blended for a smoother, more refined finish.

The traditional version is particularly appealing when small pieces of toasted nuts remain visible.

The ideal consistency is:

thick + creamy + slightly textured + glossy.

The Secret of Great Romesco

The key lies in the toasting of the ingredients.

Tomatoes.

Garlic.

Nuts.

Bread.

Each develops a different set of aromas when exposed to heat.

This combination of toasted flavours gives the sauce its remarkable depth.

The ñora provides sweetness and a distinctive fragrance.

The vinegar balances the richness of the olive oil and nuts.

And the chilli gives the final touch of personality.

What to Serve with Romesco Sauce

Romesco is exceptionally versatile.

Calçots

Its most iconic pairing.

The sauce accompanies grilled calçots and is an essential part of the traditional Catalan calçotada.

Fish

Excellent with white fish, rock fish and grilled seafood preparations.

Seafood

Works beautifully with prawns, langoustines, octopus, mussels and other Mediterranean seafood.

Meat

Excellent with chicken, pork and grilled meats.

Vegetables

Ideal with artichokes, asparagus, aubergine, peppers and other roasted vegetables.

Romesco and Calçots

An inseparable Catalan pairing

During an authentic calçotada, the sauce takes centre stage.

The calçots are grilled directly over the flames until their outer layers become heavily charred.

They are then wrapped, cleaned and served with a generous portion of sauce.

The contrast is extraordinary:

sweet smoky calçot + rich, tangy, creamy and slightly spicy Romesco.

It is one of the most recognisable combinations in Catalan gastronomy.

The Premium Magic Dreams Barcelona Touch

Catalan tradition elevated into refined gastronomy

For a Premium Magic Dreams Barcelona version, use carefully selected toasted nuts, premium extra virgin olive oil and particularly aromatic ñora peppers.

Serve the sauce in a handcrafted ceramic bowl or use it as an elegant brushstroke across the plate.

For a contemporary presentation:

Romesco base + main ingredient + toasted nuts + a few drops of olive oil.

The sauce should enhance the dish.

Never hide it.

Presentation

For a traditional table, serve the Romesco in a ceramic sauce dish at the centre of the table.

For a more refined gastronomic presentation, use a small quenelle or a broad brushstroke of sauce alongside the fish, meat or vegetables.

Finish with a few drops of extra virgin olive oil and a scattering of toasted nuts.

Pairing

For the table, we recommend a fresh 0.0% alcohol-free Mediterranean-style white wine, with good acidity to balance the richness of the nuts and olive oil.

A 0.0% alcohol-free Mediterranean rosé can also work beautifully, especially with grilled meats and vegetables.

For a completely refreshing option, serve very cold sparkling water with lemon and fresh Mediterranean herbs.

Storage

Romesco can be stored in an airtight container in the refrigerator for approximately 3–4 days.

Before serving, allow it to come closer to room temperature and stir well.

If it has become too thick, add a few drops of olive oil or a small amount of water to restore the desired consistency.

A Sauce with Catalan Identity

Romesco perfectly demonstrates how Catalan cooking can transform simple ingredients into something extraordinary.

Tomato, garlic, nuts, ñora, bread, olive oil, vinegar and a touch of heat.

Nothing complicated.

Nothing unnecessary.

Just well-treated ingredients.

Behind them lies a culinary tradition deeply connected with Tarragona, the Mediterranean and the famous calçotada.
