The great gastronomic ritual of Catalan cuisine
Calçots with Romesco sauce are much more than a recipe: they represent one of the great gastronomic rituals of Catalonia.
Closely associated with Valls and the Camp de Tarragona, calçots are a variety of tender green onion traditionally enjoyed during the Calçotada, a popular celebration that brings family and friends together around fire, embers and the table.
Their preparation is simple, but it requires respecting a very specific technique.
The calçots are placed directly over the hot embers and grilled until their outer layer becomes completely blackened and charred. This first layer protects the inside and allows the heart of the calçot to cook slowly, developing a tender, juicy and slightly sweet texture.
Then comes one of the most characteristic moments of Catalan tradition: the charred outer layer is removed, the calçot is lifted by hand and the tender white part is dipped directly into the Romesco sauce.
Romesco sauce, originally from the province of Tarragona, is the perfect accompaniment. Made with roasted tomatoes, ñora peppers, almonds, hazelnuts, garlic, olive oil and vinegar, it combines toasted, sweet and slightly acidic notes with a delicate touch of spice.
The result is an extraordinary balance between the sweetness of the calçot and the intensity of the nuts, tomato and dried pepper.
The greatness of this tradition lies precisely in its simplicity.
Fire, ingredients, sauce and company.
A deeply Mediterranean Catalan cuisine that transforms a humble ingredient into a truly memorable gastronomic experience.
Ingredients
Serves 4
For the calçots
- 40–48 fresh calçots, approximately 10–12 per person.
- Salt, optional.
- Romesco sauce, for serving.
For the Romesco Sauce
- 150 g toasted almonds.
- 100 g toasted hazelnuts.
- 2–3 ripe tomatoes.
- 2–3 ñora peppers.
- 1–2 garlic cloves.
- 1 small chili pepper or bitxo, to taste.
- 150 ml extra-virgin olive oil.
- 1 tablespoon wine vinegar.
- Salt, to taste.
Optional: a small slice of toasted bread can be added to the Romesco to give it more body and a more traditional texture.
Preparing the Romesco Sauce
01 · Prepare the ñora peppers
The aromatic depth of dried pepper
Place the ñora peppers in a bowl of hot water and leave them to soak for approximately 20–30 minutes.
Once softened, carefully remove the stems and seeds.
Using a spoon, scrape out the flesh of the ñoras and set it aside.
The ñora flesh provides a deep, slightly sweet flavor that is characteristic of Romesco sauce.
02 · Roast the tomatoes and garlic
The flavor of fire
Place the tomatoes and garlic cloves on a baking tray.
Roast them in an oven at approximately 200°C / 390°F until the tomatoes are completely tender and their skins have developed lightly charred areas.
They can also be roasted directly over embers for an even more pronounced smoky character.
Remove the tomato skins and reserve the flesh.
Peel the roasted garlic.
The objective is to create concentrated, lightly toasted flavors without burning the inside of the ingredients.
03 · Grind the nuts
The characteristic texture of Romesco
Place the toasted almonds and hazelnuts in a mortar or food processor.
Grind until finely crushed but still slightly textured.
There is no need to turn the nuts into a completely uniform flour.
A little texture gives the sauce personality and preserves its traditional character.
04 · Add the tomato and ñora
The heart of the sauce
Add the roasted tomato flesh, roasted garlic and ñora pulp to the mortar or food processor.
Add the chili pepper or bitxo.
Blend until all the ingredients are well combined.
Adjust the amount of chili according to the desired level of heat.
Romesco should have character, but the spice should not overpower the toasted and sweet flavors of the nuts and tomatoes.
05 · Emulsify with olive oil and vinegar
The Mediterranean balance
Gradually add the extra-virgin olive oil while blending or stirring continuously.
Then add the vinegar little by little.
The sauce should become creamy, glossy and slightly thick.
Taste and adjust the salt.
If the sauce is too thick, add a few drops of water to reach the desired consistency.
If it is too thin, add a small amount of additional ground nuts.
Set aside at room temperature until ready to serve.
Preparing the Calçots
06 · Prepare the calçots
A simple ingredient, a precise technique
Do not wash the calçots excessively before grilling them.
Trim the roots and remove only the outer layers that are particularly damaged or dirty.
Keep most of the outer structure intact, as this is the layer that will protect the inside during cooking over the embers.
Arrange them and have them ready beside the grill.
07 · Grill directly over the embers
Fire as an ingredient
Prepare a grill with hot, glowing embers.
Place the calçots directly over the embers without adding oil.
Grill them for approximately 10–15 minutes, depending on their size and the intensity of the heat.
Turn them as necessary so they cook evenly.
The outer layer should become completely black, charred and apparently burnt.
Do not worry about their appearance.
This blackened layer acts as a protective shell, allowing the inside to cook slowly in its own steam.
08 · Rest the calçots
The heat continues to work
Once grilled, remove the calçots from the embers.
Gather them together and, if desired, wrap them for a few minutes in newspaper or heat-resistant kitchen paper.
This short resting period allows the residual heat to finish softening the interior.
The white part should be tender, juicy and slightly sweet.
The Calçotada Ritual
09 · Clean the calçots
The traditional way to eat them
Hold the calçot by its green leaves.
With your other hand, gently pull away the charred outer layer.
The tender, white and juicy heart should be revealed.
There is no need for a perfectly clean presentation.
Part of the charm of the Calçotada is precisely the informal experience of eating with your hands and sharing the moment around the table.
10 · The meeting with Romesco
The moment everyone waits for
Hold the calçot by its green leaves and generously dip the white part into the Romesco sauce.
The sauce should cover a good portion of the calçot without completely hiding its texture.
Lift the calçot and bring it directly to your mouth.
The contrast is immediate:
sweet and juicy calçot, creamy sauce, toasted nuts, tomato, ñora and a delicate touch of spice.
Gourmet Suggestions
Magic Dreams Barcelona
To elevate this tradition without losing its essence:
- Use fresh calçots of a similar size for even cooking.
- Prepare the Romesco with freshly toasted almonds and hazelnuts to maximize their aroma.
- Roast the tomatoes and garlic slowly to develop greater depth of flavor.
- Gradually incorporate the extra-virgin olive oil to control the consistency of the sauce.
- Use a combination of almonds and hazelnuts to achieve a more complex balance of sweetness, richness and toasted notes.
- Adjust the vinegar carefully. It should provide freshness without dominating the sauce.
- For a more intense version, roast the tomatoes directly over the embers alongside the calçots.
- Romesco can be prepared several hours in advance, allowing the flavors to blend.
- Serve the sauce at room temperature so that its aromas can fully develop.
The secret to great calçots
The secret is not only the ingredient.
It is the fire.
The calçots must be cooked directly over the embers until their outer layer is completely charred.
This blackened layer may appear excessively burnt, but it is precisely what protects the inside and allows the calçot to retain its moisture.
The cooking must be intense enough to develop the aromas of the fire without destroying the heart of the vegetable.
The perfect interior should be:
tender, juicy, sweet and lightly smoky.
The Secret to Great Romesco
A good Romesco sauce should maintain a balance between five essential elements:
tomato, ñora, nuts, olive oil and acidity.
The nuts provide body and richness.
The tomato contributes sweetness and freshness.
The ñora adds depth.
The olive oil brings all the flavors together.
And the vinegar provides the acidity needed to prevent the sauce from becoming too heavy.
The heat should be used with moderation.
The perfect sauce is not necessarily the hottest one, but the one in which every ingredient can still be recognized.
Gourmet Presentation
For a gastronomic presentation, we can preserve the spirit of the traditional Calçotada by using a handmade ceramic platter or a rustic-style serving dish.
Arrange the grilled calçots in a small group and serve the Romesco separately in a bowl.
For a contemporary presentation, carefully clean some of the calçots and arrange them parallel on a plate.
Add small brushstrokes or dots of Romesco sauce around them.
Finish with a few drops of extra-virgin olive oil, lightly crushed toasted hazelnuts and small Mediterranean herb leaves.
We can also leave one calçot partially cleaned to visually represent the transformation created by the fire.
The presentation should always maintain a connection with its origins:
a rural Catalan recipe transformed into an elegant gastronomic experience without losing its popular soul.
Service
Calçots should be served freshly grilled and still hot.
Traditionally, they are wrapped in paper to retain their heat and moisture.
Romesco should be served separately, preferably at room temperature.
During a traditional Calçotada, diners clean the calçots with their hands and eat them directly.
For a gastronomic service, the calçots can be presented already cleaned and accompanied by small portions of Romesco.
In both cases, the goal is the same:
to enjoy the contrast between the sweet, smoky vegetable and the intense sauce made with nuts and tomato.
Pairing
Calçots with Romesco pair particularly well with a fresh Catalan 0.0% alcohol-free white wine with good acidity.
A Mediterranean-style white wine helps cleanse the palate after the richness of the nuts and olive oil.
They can also be served with an artisanal 0.0% alcohol-free vermouth, particularly when enjoyed as an aperitif.
For a completely refreshing option, very cold sparkling water with a few drops of lemon works beautifully.
Make-Ahead Preparation
The Romesco sauce can be prepared several hours in advance or even the day before.
In fact, resting allows the flavors of the ñora, tomato, garlic and nuts to blend together more harmoniously.
Before serving, stir the sauce and adjust its consistency with a few drops of water or extra-virgin olive oil.
The calçots, however, should be grilled as close to serving time as possible.
The gastronomic experience depends greatly on enjoying them hot, tender and freshly removed from the embers.
Storage
Romesco sauce: can be stored in an airtight container in the refrigerator for approximately 3–4 days.
Before serving, allow it to sit at room temperature for a few minutes and stir well.
Grilled calçots: are best eaten immediately. If necessary, they can be refrigerated for approximately 1–2 days, although they will lose some of their texture and smoky aroma.
We do not recommend freezing already grilled calçots.
Romesco sauce, however, can be frozen, although its texture may change slightly after thawing.
