A bowl of nước chấm
Nước mắm pha
Nước mắm pha (mixed fish sauce) is the most well known dipping sauce made from fish sauce. Its simplest recipe is some lime juice, or occasionally vinegar, one part fish sauce (nước mắm), one part sugar and two parts water. Vegetarians create nước chấm chay (vegetable sauce) or nước tương (soy water) by substituting Maggi seasoning sauce for fish sauce (nước mắm).
To this, people will usually add minced uncooked garlic, chopped or minced Bird's eye chilis, and in some instances, shredded pickled carrot/white radish and green papaya for bún. Otherwise, when having seafood, such as eels, people also serve some slices of lemongrass.
It is often prepared hot on a stove to dissolve the sugar more quickly, then cooled. The flavor can be varied depending on the individual's preference, but it is generally described as pungent and distinct, sweet yet sour, and sometimes spicy.
Varieties by regions
People in the north of Vietnam tend to use nước mắm pha, as cooked by using the above recipes, but add broth made from pork loin and penaeid shrimp (tôm he). In the central section of the country, people like using a less dilute form of nước mắm pha that has the same proportions of fish sauce, lime, and sugar as the recipe above, but less water, and with fresh chili. Southern Vietnamese people often use palm sugar and coconut water as the sweetener.
Nước mắm pha is typically served with:
- Cơm tấm, a rice dish with meat, poultry, eggs, seafood or vegetables. The toppings are often fried, grilled, braised, steamed/boiled, or stir-fried.
- Chả giò, spring rolls
- Gỏi cuốn, which are sometimes called shrimp salad rolls or "rice paper" rolls, or erroneously as spring rolls (Alternately, gỏi cuốn are served with a peanut sauce containing hoisin sauce and sometimes chili, or tương xào made from tương, a Vietnamese fermented bean paste/soy sauce.)
- Bánh cuốn or "rice rolls", where wide sheets of rice noodles rolled up, and topped (or stuffed) with stir-fried or braised meat or seafood, with soy sauce or fish sauce
- Bánh xèo, a pan-fried crepe made from rice flour and coconut milk, and filled with pork, shrimp, onion and bean sprouts, and topped with herbs
- Bánh hỏi, very thin vermicelli layered into sheets, and separated by thin layers of mỡ hành (scallions in oil)
- Bún, rice noodles with meat, poultry, eggs, seafood or vegetables. The toppings are often fried, grilled, braised, steamed/boiled, or stir-fried.
