The Anchovy Tin: Decoding Yields, Grading, and the Science of the Melt

Anchovies are graded by size and weight before they ever reach the tin. In the industry, this is often a matter of Fillet Integrity. Lower-cost commodity tins use smaller fish to reach the 2oz weight requirement, resulting in more fillets (up to 12) that may be prone to fragmentation. Premium producers prioritize larger, heartier fish, which is why a jar of Agostino Recca might only contain 6 to 8 substantial fillets.

Anchovies: Engraulis encrasicolus (Mediterranean or European Anchovy)

Anchovies are fish of the family Engraulidae, which is comprised of about 140 species. Found in all the world’s warm oceans, they are small fish commonly known as ‘forage’ fish since they are eaten by larger fish, sea birds, and mammals.

These fish have long been used for various culinary purposes. There are several commercial species but the most famous for cooking is Engraulis encrasicolus, better known as the Mediterranean or European anchovy. They are found in the Mediterranean, the Black Sea, and the warmer waters off the East Atlantic coasts.

🐟 The Weird Mystery of Fish Texture Ever wonder why an anchovy fillet practically dissolves in a pan while a steak stays tough? It’s all about the myotomes. Fish have a unique “W-shaped” muscle structure and significantly less collagen than land animals, which is why they offer that signature flaky snap—or in the case of anchovies, the ability to “melt” into a sauce.

Why and How Anchovies Are Used

Anchovies can be used anywhere a salty umami or savory flavor is desired and as long as small enough amounts are used, there should not be any noticeable fishiness. However, some are more sensitive to the flavor than others and may scoff at the additions of this strongly flavored preserved fish.

Usually in small quantities, anchovies are added to pizzas, pasta, and many other dishes. They are an important ingredient in the dressing for Caesar salad and are a part of Worcestershire sauce and many other fish sauces, as well as French remoulade.

The Science of the Melt: Proteolysis and Myotomes

While most fish provide a flaky “snap,” the anchovy is prized for its ability to seemingly “melt” into a sauce or oil. This isn’t just luck; it’s a result of proteolysis. During the traditional salt-curing process, natural enzymes break down the fish’s proteins into smaller, more soluble compounds.

Because fish have a unique “W-shaped” myotome muscle structure and significantly less collagen than land animals, this enzymatic breakdown transforms the fillet into a smooth, savory paste when heat is applied. This is why a single fillet can vanish into a pan of olive oil, leaving behind deep flavor without the texture of solid fish.

Umami Synergism: The Culinary Bridge

Anchovies are more than just “salty”; they are a concentrated source of glutamates and inosinates. When these compounds interact, they create Umami Synergism, a chemical reaction that makes everything else in the dish taste more intense.

This is why they are the foundational “bridge” in the Mediterranean, acting as the savory anchor in everything from Worcestershire sauce to a classic Caesar dressing. They don’t just add fish flavor; they heighten the complexity of the proteins and vegetables they are paired with.

Therefore, just as soy sauce and and fish sauce provide the essential umami flavor in Asian foods, anchovies can be thought of as the umami flavor of the Mediterranean, providing a savory and briny depth to dishes.

For a classic Caesar dressing, anchovies are mashed into a paste with garlic and a mortar and pestle is used to make blend the anchovies into an emulsion with egg yolks and oil. Today, high-speed blender can be used to create the same effect.

Typical Anchovy Yield for Ingredient Conversion

Anchovies now come packed in various ways, including in jars. A jar of anchovies can be of varying sizes and weights. However, most people are familiar with anchovies in a can. A typical can of anchovies is 2 ounces. You may also need ingredient conversions for anchovy paste if you are substituting it for canned or fillets. Here are the typical yields so you can find out how many anchovies a 2-oz can contains, as well as other variations.

Depending on how your recipe lists the amount of anchovies to use, these conversations can help you figure out how much to buy or use when substituting one form of anchovies for another.
