Salmon with Tomato, Dill, and Garlic Soup
When riêu is brought to the table, expect a full-bodied soup laced with rich-tasting seafood and tangy tomato. Viet cooks prepare a fish riêu like this one as an everyday canh, or the more extravagant crab and shrimp riêu noodle soup (page 215) for a special occasion. Carp is the fish typically used in this soup, but since it is not commonly available at regular markets, my family switched to salmon, which has the fattiness to pair perfectly with the tomato, dill, and garlic of a classic riêu. We used salmon steaks for years because the bones and skin enriched the broth. But steaks can be difficult to handle during cooking and later on in the bowl, so I now use salmon fillet. In the classic northern Vietnamese tradition, the fish is seared first to firm its flesh. The searing not only helps the fish hold its shape, but also provides a nice textural contrast in the finished soup.

Ingredients
Preparation
Step 1
Briefly blot the salmon dry with a paper towel before cutting it into 1-inch chunks. In a nonstick skillet, heat the 1/2 teaspoon oil over medium-high heat. Add the salmon and sear, turning once, for 1 to 2 minutes on each side, or until lightly browned. The fish will cook further in the soup. Transfer to a plate and set aside.
Step 2
In a 3- or 4-quart saucepan, heat the remaining 1 tablespoon oil over medium heat. Add the onion and cook gently, stirring occasionally, for about 4 minutes, or until fragrant and soft. Add the tomatoes and salt, cover, and simmer for about 4 minutes, or until the tomatoes have collapsed. Uncover and add the salmon, fish sauce, and water. Raise the heat to high and bring to a boil, using a ladle to skim and discard any scum that rises to the surface. Lower the heat to a gentle simmer, so that the ingredients dance in the broth. Cook for 15 minutes to develop and concentrate the flavors. If you are not serving the soup right away, turn off the heat and cover.
Step 3
Just before serving, return the soup to a simmer. Taste and add extra salt or fish sauce, if necessary. Add the dill and garlic and turn off the heat. Ladle into a serving bowl and sprinkle with the pepper. Serve immediately.
