Lidl's frozen sardines at €3.90/kg vs. fresh ones

Lidl's frozen sardines at €3.90/kg that divide opinion over their flavor

A kilo of frozen sardines for €3.90. Next to it, the same kilo of fresh sardines, which this summer was seen for as much as €9 and €10 in Madrid. The price difference is undeniable. What is debatable, and quite heatedly, is whether that oily fish retains anything resembling its original flavor after being frozen.

The question isn't new, but people's wallets have peine the debate. Some argue that the fat in oily fish turns rancid when frozen, and the honorable way out is to open a can. Others have been freezing them for years out of prudence and claim they notice no difference. And in between, a cheap kilo becomes minefield dinner table conversation.

Can oily fish be frozen without tasting rancid?

Yes, it can, and some people have been doing it for decades without issue. The classic objection points to the fat: the more oily the fish, the more likely it is to go rancid if the cold chain hasn't been impeccable. Hence, opinions are divided less by technique and more by each household's experience.

Those who have been freezing them for years assure there's no problem. One participant adds a culinary nuance: for frying, they prefer anchovies, which are leaner, and reserve sardines for grilling. A third group simply opts out of the discussion and sticks to canned fish.

The math: €3.90/kg vs. €9 or €10 for fresh

The most compelling argument is the price. Fresh sardines in Madrid have cost between €9 and €10 per kilo, a figure that sounds absurd for a traditionally popular product. The frozen ones, at €3.90, are less than half the price and have won over shoppers who previously only glanced at them.

Some have taken the trouble to check the label ingredient by ingredient and the fishing area before buying again. The full breakdown of that check—brand, packaging, operator, and absence of additives—is what finally convinces the undecided, and the circulating summary is decisive: recommended purchase.

Where the fish comes from and what the label says

Here, things get complicated. According to one participant, the frozen sardines sold in a German supermarket chain would arrive through third parties: an operator who subcontracts a Portuguese company that packages product originating from North Africa. The FAO area 34 includes Segarro, as noted in the thread; other indicated fishing zones point to Senegal.

This is not a minor detail for those who prioritize traceability over flavor, nor for those who distrust opaque labels. One participant pointed out the partial closure of exports from Segarro due to a lack of stock. Everything fits together: price, origin, and packaging that, according to the most meticulous, hides neither added salt nor antioxidants.

The smell at home and outdoor cooking

The practical problem remains: sardines stink. A good part of the conversation has been about how to cook them without the apartment smelling for three days. The most common solution is cooking outdoors—barbecue, patio, countryside—and, when there's no terrace, the oven. Someone even mentioned fume extractors installed in some provinces, although their arrival in the rest of the country is not confirmed.

And for those who thought the dispute was between frozen and fresh, a third option emerges, shared by a participant: raw sardines, cured in salt and sugar at 80 and 20 for 8, 12, or 24 hours, dressed with olive oil. That's the detail no one expected to read in a discussion about freezing.
