Mercadona's smoked eel is satisfactory, but the difference from an artisanal one is notable: firmer texture, deeper flavor, and no additives. In this comparison, we analyze ingredients, smoking process, flavor, texture, price per kilo, and value for money, to help you make an informed decision.
What is smoked eel and why is it a gourmet product
Smoked eel is one of the most prized products in European gastronomy. In the Netherlands, Germany, and Denmark, it is a Christmas and celebratory classic. In Spain, its consumption is growing among gourmet consumers seeking distinct flavors, unctuous textures, and products with a history.
Eel has fatty flesh (up to 25% fat), which makes it a perfect candidate for smoking. The fat acts as a vehicle for the smoky flavor and maintains juiciness during the process. The result is a silky, almost buttery texture, with a deep flavor that combines sweet, salty, and smoky notes.
But not all smoked eels are equal. The smoking method, the quality of the raw material, and the additives used make significant differences. Let's look at the options.
Mercadona's smoked eel: what it offers
Mercadona sells smoked eel under its Hacendado brand, usually in a refrigerated tray format (100-150 g). It is an accessible product that can be found relatively easily in the smoked foods section alongside salmon and roe.
Pros:
- Affordable price: between €5-7 per tray (about €40-50/kg)
- Availability: in most Mercadona stores, especially during the Christmas season
- Convenient presentation: ready to eat, vacuum-packed
Cons:
- Smoked with liquid smoke (smoke flavor) in many references, not traditional wood smoking
- May contain additives such as preservatives E-250 (sodium nitrite) and colorants
- Softer and less defined texture than artisanal
- Milder and less complex smoky flavor
Artisanal smoked eel: what makes it different
Artisanal smoked eel is made with cold or hot smoking using real wood (beech, oak, or apple), over hours or even days. The smoke slowly penetrates the flesh, creating layers of flavor that liquid smoke cannot replicate.
Key differences:
- Real wood smoking: Beech or oak for 4-12 hours. The flavor has depth, woody nuances, and a clean aftertaste.
- No additives: Only eel, salt, and smoke. No nitrites, no colorants, no artificial flavors.
- Firm and unctuous texture: The fat is better distributed, the flesh has more structure.
- Traceable origin: Usually with origin certification and complete traceability.
Detailed comparison: Mercadona vs artisanal
| Aspect | Mercadona | Artisanal |
|---|---|---|
| Price/kg | €40-50 | €80-130 |
| Smoking method | Liquid smoke / flavor | Real wood (beech/oak) |
| Additives | E-250, possible colorants | Only salt and smoke |
| Texture | Soft, somewhat watery | Firm, unctuous |
| Smoked flavor | Mild, linear | Complex, nuanced |
| Availability | High (supermarket) | Gourmet stores / online |
Ingredients and additives: read the label
The fundamental difference lies in the ingredient list. A quality artisanal smoked eel has 3 ingredients: eel, salt, and wood smoke. Period.
The industrial version may include: eel, salt, smoke flavor (liquid smoke), dextrose, E-250 (sodium nitrite), E-316 (sodium erythorbate), colorant (caramel). None of these additives are dangerous in the quantities used, but they alter the product's taste and experience.
Liquid smoke deserves special mention: it is an aqueous solution obtained by condensing real smoke. Technically it is smoke, but applied by immersion or spraying, not by slow exposure to natural smoke. The result is a flatter smoky flavor, without the layers and nuances that traditional smoking provides.
Taste and texture: what really matters
Mercadona: Mild and pleasant smoked flavor, but one-dimensional. The texture tends to be softer and somewhat watery. It works perfectly as a casual appetizer or on toast with cream cheese. It doesn't disappoint, but it doesn't surprise either.
Artisanal: Real wood smoking provides layers of flavor — first sweet notes from the eel fat, then woody smoke, and a clean, lingering aftertaste. The texture is firmer, almost melting into buttery flakes. It is a distinct gastronomic experience, not just a distinct product.
Is the price difference worth it? It depends on the context. For an informal appetizer, Mercadona's is fine. For a special dinner, a Christmas platter, or a gourmet gift, artisanal justifies every euro.
How to serve smoked eel
Plain, at room temperature: The purest way. Take it out of the refrigerator 15 minutes before serving so the fat can warm up and release its full aroma. Slice it thinly.
On toast: Toasted rye bread, cream cheese, smoked eel, fresh dill, and a squeeze of lemon. The Nordic classic that never fails.
With scrambled eggs: Crumble the smoked eel over creamy scrambled eggs. The fat-smoke-egg combination is addictive.
In a warm salad: Over mixed greens with a mustard vinaigrette, red onion, and capers. An elegant starter in 5 minutes.

Conclusion
Mercadona's smoked eel is a decent product for the price you pay. If you just want to try smoked eel or need something quick for an appetizer, it's fine.
But if you are looking for the real experience—wood smoking, unctuous texture, layered flavor—the artisanal version is incomparable. As with many gourmet products, the difference lies in the details that industrial production cannot replicate at scale.
