The Umami-Packed Ingredient That Upgrades Tuna Salad Sandwiches

One of the fastest ways to improve your tuna salad is to amp up its savory flavor with another ingredient of the sea: Fish sauce.

Fish sauce is packed with glutamates, the amino acids that trigger the savory umami flavor. When fish sauce is added to tuna salad it shouldn't overpower the other flavors.

Add a small amount to increase the flavor of the tuna. Other umami-rich ingredients like Worcestershire or soy sauce can add strong flavors, throwing off the balance of the dish.

When selecting a bottle of fish sauce, look for one with a short ingredient list featuring items like water, salt, and anchovies.
