The Curing Process: Why Salt is Essential for Anchovies
Anchovies are small, oily fish that are highly perishable when fresh. To preserve them for transport and storage, they are traditionally cured in salt. This process draws out moisture from the fish, which inhibits the growth of bacteria and prevents spoilage. The amount of time the fish are cured, often between six and twelve months, directly influences their final saltiness and flavor intensity. The curing process also develops the characteristic umami, or savory flavor, that anchovies are famous for. The resulting product is a concentrated, semi-preserved ingredient known for its powerful flavor. However, this necessity for preservation is what leads to the high sodium levels found in most commercially available tins and jars.
The Difference Between Fresh and Cured Anchovies
Many people are surprised to learn that freshly caught anchovies are not inherently salty at all. They have a delicate, mild flavor that is a stark contrast to their cured counterparts. The canning or jarring process, which is the most common way to find anchovies in stores, involves heavily salting and curing the fillets. Some are packed in salt, while others are stored in oil, but both methods rely on a heavy salt presence for preservation.
How to Reduce the Saltiness of Anchovies
For those who love the umami flavor of anchovies but want to reduce their sodium intake, several simple preparation techniques can make a significant difference. By taking a few extra minutes to prep your fish, you can wash away a surprising amount of salt without losing the deep, savory character.
Here's a step-by-step guide to desalting salt-packed or oil-packed anchovies:
- Rinsing: For a quick reduction in saltiness, rinse the fillets under cold running water. Gently rub off any excess surface salt or brine. This method is effective for a milder change.
- Soaking: For a more substantial reduction, soak the anchovies in water, milk, or white wine for 15 to 30 minutes. This draws out more salt from the fish's flesh. Soak time depends on the anchovy's firmness; be careful not to over-soak, which can make them mushy.
- Patting Dry: After rinsing or soaking, pat the anchovies thoroughly dry with a paper towel. Removing excess moisture is important, especially if you plan to store the remaining fillets.
- Filleting and Storing: For salt-packed varieties, you will also need to fillet the anchovies and remove the bones before using them. Once cleaned, store them in a clean jar, fully submerged in olive oil in the refrigerator for future use.
Anchovies vs. Sardines: A Sodium Comparison
While anchovies and sardines are often mentioned in the same breath, their sodium levels can differ drastically, particularly in their preserved forms. Both are healthy, oily fish rich in omega-3 fatty acids, but their canning processes set them apart significantly. The table below highlights some key nutritional differences based on canned varieties.
| Nutrient (per 100g serving) | Canned Anchovies | Canned Sardines | 
|---|---|---|
| Sodium | 153% of DV | 21% of DV | 
| Protein | 29 grams | 25 grams | 
| Iron | 26% of DV | 16% of DV | 
| Selenium | 97% of DV | 75% of DV | 
| Vitamin B12 | 15% of DV | 149% of DV | 
| Omega-3s | Very high | Very high | 
Note: Nutrient percentages are based on approximate daily values (DV) and may vary by brand and product.
Choosing the Right Anchovies for Your Needs
Not all anchovy products are created equal when it comes to salt content and preparation. Your choice should depend on your cooking application and dietary needs.
Finding Lower-Sodium Options
While traditionally cured anchovies are high in salt, some brands and products offer lower-sodium alternatives. Look for these products specifically labeled as 'low-salt' or 'reduced sodium.' Another excellent option is boquerones, which are fresh white anchovies marinated in vinegar and olive oil, resulting in a much milder, less salty flavor. For the most control over sodium, consider seeking out fresh anchovies from a specialty fishmonger and preparing them yourself, though this requires more effort.
Salt-Packed vs. Oil-Packed
Anchovies are available in both salt-packed and oil-packed forms. Salt-packed anchovies require more preparation, as you must rinse and fillet them, but this also gives you the most control over the final saltiness. Oil-packed anchovy fillets are pre-filleted and ready to use, making them a convenient option, but their sodium level is set by the manufacturer. High-quality oil-packed brands tend to be less excessively salty than budget brands.
Health Implications of Sodium in Anchovies
The high sodium content of traditionally cured anchovies should be a consideration for those with certain health conditions, such as high blood pressure, diabetes, or kidney disease. A diet high in sodium can increase blood pressure, which is a major risk factor for heart disease and stroke. However, because anchovies are typically used in small quantities to add flavor, they do not pose a significant risk for most people when consumed in moderation. A small amount of mashed anchovy adds a powerful umami punch without contributing a large amount of sodium to the overall dish. The healthy omega-3 fatty acids in anchovies provide numerous health benefits, making them a nutritious ingredient despite the saltiness. As always, balance and moderation are key to a healthy diet.
Conclusion: Navigating the Saltiness of Anchovies
Ultimately, whether there is 'too much salt in anchovies' is a matter of perception and preparation. While their cured forms are undeniably high in sodium, this is a byproduct of a necessary and flavor-enhancing preservation method. By understanding the difference between fresh and processed anchovies, and by using simple techniques like rinsing and soaking, consumers can enjoy the delicious, savory benefits of this nutritious fish while effectively managing their sodium intake. Choosing high-quality brands or exploring marinated and lower-sodium options also provides flexibility. The high concentration of beneficial omega-3s, protein, and minerals means anchovies can remain a valuable part of a balanced diet, so long as their preparation is taken into account.

The Health-Conscious Way to Enjoy Anchovies
- Rinse Before Use: Always rinse oil-packed or salt-packed anchovies under cold water to wash away excess surface salt, reducing sodium.
- Soak for De-salting: For more intense salt reduction, soak fillets in water or milk for 15-30 minutes, testing for desired salinity.
- Use as a Flavor Booster: Anchovies' strong flavor means only a small amount is needed to add a significant umami dimension to sauces and dressings.
- Explore Alternative Forms: Try marinated white anchovies (boquerones) or anchovy paste for different flavor profiles and potentially lower sodium.
- Moderate Consumption: Since they are nutrient-dense, consuming anchovies in smaller quantities is a healthier approach for overall dietary sodium management.
