Despite their reputation as oily, smelly, fatty and usually packed in a tin, there’s lot to like about anchovies, sardines and smelt. They’re extremely flavorful, loaded with healthy omega-3s and abundant in our oceans. And while small fish are found most often on menus in Caesar salads, atop pizzas or inside sushi rolls, lately more chefs are using them in appetizers or entrees.

According to Datassential MenuTrends, 21 percent of all restaurant menus feature at least one variety of small fish, an increase of 2 percent since 2009. They can be found most often at fine-dining restaurants, where 36 percent of menus feature a small fish. Anchovies, appearing on 19 percent of menus, are the most common small fish offered by restaurants.

Their rarity on menus, along with and their distinct flavor, is precisely why chef Joe Realmuto loves to put anchovies, sardines and smelts on the menu at Nick & Toni’s East Hampton and Nick & Toni’s Café in New York City.

"Besides the fact they are delicious, they are not usually found on menus, which is a big turn-on for me,” said Realmuto. “I like to feature things that are not just run of the mill.”

Realmuto likes to prepare little fish whole and simply, allowing their natural flavor to shine. For example, he likes to roast sardines in the restaurant’s wood-burning ovens and serve them with a fennel citrus salad. Another favorite preparation is fish French fries, which are fried smelts that are lightly battered and served with a bit of aioli.

While these little fish dishes aren’t necessarily big sellers, Realmuto says they are standouts on the menu. “I like to put what I call ‘sleepers’ on the menu,” he said. “We know they aren’t going to be big sellers, but when [diners] try it they love it.”

Though he can’t predict how they’ll sell, chef Eldad Shem-Tov will certainly include an appetizer of sardines or anchovies on the menu at New York City’s soon-to-be-opened Whitman & Bloom Liquor Company.

“Usually people are not using those fishes on the menu here. People are usually afraid of what we used to get in a can,” said Shem-Tov. “When they are really fresh, the taste is delicate. I’m coming from the Mediterranean, and we do use them a lot.”

Shem-Tov will house-pickle fresh sardines or anchovies and serve them for lunch and dinner in a number of preparations, such as over rustic tomato sauce or with roasted pepper on brushcetta. He even plans to serve them as they often do in Greece, on brioche or challah with butter for brunch.
