What is Nuoc Mam Cham?
Vietnamese Nuoc Mam Cham, also known as simply Nuoc Cham / Nuoc Mam, is traditionally used as a dipping sauce or salad dressing, but you can also use it bring extra oomph to other Asian dishes that would benefit from its sweet-salty-sour flavour profile.
What You’ll Need
All you need for this Vietnamese dipping sauce is water, fish sauce, rice vinegar, lime juice, sugar, garlic and fresh chilli. We’ve made this recipe perfect for one serving or on a share platter, but it’s also very easy to scale it up to store for later or serve more people.

Fish Sauce
Fish sauce is a powerful, intensely flavoured ingredient ready to add a savoury flavour boost to your cooking. We usually have Squid Brand or Three Crabs fish sauce in the cupboard. You should be able to find fish sauce in the Asian aisle of your local supermarket, or at an Asian supermarket. Otherwise, it’s also available online.
If you need to substitute, we recommend using soy sauce, which is made from soybeans and wheat. It’s also a great alternative for vegans.
Rice Vinegar
Like the name implies, this vinegar is made from rice through fermentation. Unlike regular white vinegar, it’s sweeter and less acidic. The varieties found at Asian supermarkets are usually Chinese or Japanese in origin and are fine to use for this recipe, or you can purchase online.
If you can’t find rice vinegar, you can substitute with apple cider vinegar. If you’re in a real pinch, you can use lemon juice or regular vinegar but both will alter the taste slightly.
How to make Nuoc Mam Cham:

Wandercook’s Tips
- For the best flavour, serve immediately and at room temperature. You can also add more of any ingredient to suit your flavour preferences.
- Use this sauce for dipping spring rolls, cold rolls, pork, chicken or seafood, as well as drizzling over rice dishes or noodle salads.
- You can use hot water to help dissolve the sugar faster. Then allow to cool before serving.
- Finely chop the chilli and garlic, so you don’t end up crunching on a large chunk!

Variations & Substitutes
- We love using the fiery small Thai red chillies in this recipe, but any hot chillies you have on hand will work perfectly. Just make sure to adjust the amount until you have the perfect spicy heat to suit your tastebuds.
- For a vegan version, swap the fish sauce for soy sauce. (Optionally, make sure the soy sauce has no gluten to keep this recipe gluten free.)
- You can use lemon instead of lime juice, this will only slightly change the flavour while still giving the sauce its classic sour flavour. You can also use bottle lime or lemon juice if that’s easier to source than the fresh fruit, although the flavour won’t be quite as zingy.
- Some versions of this recipe are made with soda like lemonade or 7Up instead of still water.

When it’s this easy to make and tastes sooo good, you’ll never want to buy store-bought dipping sauce again!
