During the December season, cod is one of the most sought-after — and most substituted — products in the market. This guide explains how to identify authentic cod, recognize quality signs, and make purchases without being deceived for Christmas.
What is Authentic Cod
In Mexican Christmas cuisine, cod refers to salted cod, a white fish that has been preserved through salting and must be soaked before cooking. Its flesh is firm, with defined fibers, and has the ability to absorb flavors from tomatoes, olive oil, olives, and capers without falling apart.
The issue arises when the term “cod” is used generically. In high season, other salted fish species — more economical and with a distinct texture — are offered as if they were cod, such as cazón, completely altering the dish’s outcome.
1. Read the Label: The First Filter
When buying cod in packages, the label is the consumer’s first tool. A reliable product should clearly indicate that it’s cod, specify if it’s salted or desalted, and detail conservation conditions.
Vague descriptions like “salted fish,” “filet-type cod,” or “cod style” are warning signs. Also, be cautious of excessively uniform presentations or perfect filets: authentic cod is usually sold in loins or irregular pieces, not generic cuts.
2. Recognizing Good Cod at a Glance
In markets and fishmongers, where cod is sold by the bulk, visual inspection is crucial. The color should be ivory white, without dark stains, green zones, or pronounced yellow spots. The surface should appear dry and firm, with visible salt but no excessive wetness.
A cod that looks “sweaty,” overly wet, or has abnormal shine may indicate poor preservation. The smell is also decisive: it should smell like clean, salted fish, never rancid or sour. If the smell raises doubts, it’s best not to buy.
3. Texture Doesn’t Lie
Firmness is one of the great virtues of authentic cod. To touch, it shouldn’t feel soft or break easily. That structure is what allows the cod to maintain its shape in the sauce after desalting and cooking.
Substitutes behave differently: they disintegrate, release too much water or lose consistency when cooked, directly affecting the texture of traditional dishes like cod vizcaína.
4. Price as a Warning Sign
Cod is an expensive product, especially in December. Its importation, processing, and high demand naturally elevate its price. Therefore, an excessively cheap cod should raise red flags.
When the cost is significantly below the market average, it’s likely not authentic cod. In these cases, the initial savings usually translate into a poor culinary experience.
5. Where to Shop with Greater Security
Supermarkets offer greater traceability thanks to labeling, though they are not error-free. Traditional fishmongers can be an excellent option if you choose establishments with a good reputation, high product turnover, and visible hygiene and refrigeration conditions.
Asking questions isn’t excessive. Knowing the species, how it should be preserved, and how long it’s been on sale is part of responsible consumption, especially when dealing with a central ingredient for the Christmas dinner.
