When the heat settles in Valencia and the months without an “r” sneak onto the calendar (May, June, July and August), one of the sea’s most anticipated delicacies makes its entrance: the clòtxina valenciana, or Valencian mussel. Small, tender, and intensely briny, this seasonal bivalve is a true local gem and a key part of Valencia’s culinary soul.
At Llisa Negra, seasonal produce doesn’t just guide our kitchen, it’s something we celebrate. True to our commitment to local, product-driven cuisine, we treat the Valencian mussel for what it is: a singular ingredient, nurtured by the Mediterranean and generations of “clotxineros” (people that has dedicated their whole life to this bivalve).
It’s only cultivated here in the Valencian Region, in 22 rafts located in the outer harbour of Valencia and Sagunto, using traditional methods tied directly to the lunar cycle. The result? A product that’s rare, intense, and utterly unique, which is exactly why it’s so sought after.
What is the Valencian clòtxina, and why isn’t it just a regular mussel?
At first glance, it may resemble the better-known Galician mussel. But the clòtxina valenciana (Mytilus galloprovincialis) tells a very different story. It’s smaller, paler, and more succulent, with a deeper, more oceanic flavour shaped by the way it’s raised. In València, we say it plain and simple: “açò és mel de romer” (this it’s rosemary honey, which means, it is excellent and full of deepness).
It even boasts a “protected designation of origin” (PDO) and a distinct quality seal, which guarantees not just its provenance but a deeply artisanal production method, passed down through generations.
The lunar calendar decides the season
Yes, you read that right. Valencian mussels aren’t harvested when it’s convenient, they’re harvested when the moon says so. The season begins with April’s full moon and ends with August’s waning moon. The peak? Between May and June, when their size and flavour are at their best.
That’s why we always say Valencian mussels belong to the months without an “r”. A simple rule of thumb for knowing when they’re at their finest.
A traditional process from sea to table
The clotxineros follow nature’s calendar. The encordà (when baby mussels are tied onto ropes) begins with the waxing moon of May. Then, they’re left to grow underwater, feeding on phytoplankton and marine nutrients until they hit their perfect point. No shortcuts. No rushing. Just time, sea, and tradition.
Production is limited, which makes them all the more special. Every time they reach our kitchen, we know we’re holding something exceptional.
In colder months, they grow more slowly, but the flavor deepens. Every harvest is slightly different, and always unrepeatable.
Before reaching your plate, they spend 12 to 15 hours in a purification system to ensure safety, then are packed into 1 or 5 kilo nets. For peak flavor, always buy them fresh, and eat them the same day.
Nutritional Benefits of Valencian mussels
Beyond taste, the Valencian mussel is incredibly nutritious, ideal for those looking for healthy eating without giving up on flavour. Here’s what it offers:
- Rich in Omega-3
- High-quality protein source
- Low in calories
- Packed with minerals: calcium, magnesium, phosphorus, potassium, sodium, iron, and iodine
- Excellent source of B vitamins, especially B12
How we prepare Valencian mussels at Llisa Negra
At Llisa Negra, we treat Valencian mussels, clòtxinas, with the same respect we give to every great ingredient. Over the years, we’ve always leaned into simplicity:
- Steamed, with lemon, pepper, bay leaf, or paprika. A classic. Nothing to hide. Lemon not only pairs well, it helps your body absorb the iron they naturally contain.
- Grilled over the Josper, served with a sherry reduction, slivered almonds, fresh parsley, and a touch of oil aged in amontillado sherry casks, or with a beurre blanc sauce.

But like any bold ingredient, the Valencian mussel invites creativity. And while we keep it simple, we know other local chefs have reimagined it with flair:
- At Vuelve Carolina, Gonzalo Silla has taken them on an Asian journey: cooked with curry and coconut milk.
- When Mercatbar was open, Ana Llop served them escabeche-style, with a base of garlic, cinnamon, bay, pepper, and the mussels themselves, finished with ForVm vinegar and left to rest for 30 minutes.
These approaches prove just how versatile this mollusk can be, both in traditional and inventive kitchens.
Why choose a product-driven restaurant in Valencia?
Because real cooking starts at the source. Every ingredient has a story, a farmer, a region, and a perfect moment. And our mission as a restaurant is to listen to that story and tell it through every plate. Valencian mussels embody this perfectly: fleeting, local, full of flavor, and deeply ours.
So don’t hesitate, if you’re visiting Valencia between May and August, ask for clòtxinas. You’re about to discover one of the Mediterranean’s greatest pleasures, and one more reason to fall in love with Valencian cuisine.
