- Chili garlic sauce - (optional) if you want the sauce extra spicy.
- Carrots - Add this in right before serving so the carrots stay crunchy.

Frequently asked questions
In Vietnamese, Nước chấm means "sauce" which can refer to any kind of sauce in general. Whereas, Nước mắm means "fish sauce"which is the main ingredient in this dipping sauce.
If you plan to make this ahead, I would leave out the carrots as they can wilt. Then store it in the refrigerator for up to 2 weeks. The saltiness of the sauce helps it stay fresh for longer.
Serving Suggestions

- 2 teaspoons rice wine vinegar - - see Note 3
- 1 clove garlic - - finely diced
- 1 small Thai chili pepper - - finely diced
- 1 Tablespoon shredded carrot

✎ Recipe Notes
- Fish sauce brands: Different brands of fish sauce vary by saltiness and intensity. You may need to adjust the amounts slightly to according to your taste. If you find it too salty, add more water and sugar. For a tangier sauce add more lime juice or vinegar.
- For a vegan/vegetarian option: replace the fish sauce with light soy sauce. Dark soy sauce overwhelms the sauce and makes it too dark.
- You can skip the vinegar and replace the amount with lime juice but I prefer adding a bit of vinegar because it gives the sauce a bright flavor that the lime juice lacks. The lime juice adds a nice citrus flavor but isn't as tangy as vinegar.
- Storing leftovers: Place leftovers in an airtight container in the fridge for up to one week.
- Make ahead: If you plan on making this ahead, leave out the shredded carrots and store the sauce in the fridge for up to 2 weeks. Add the shredded carrots right before serving.
- Serve with these fresh vegetarian summer rolls.

This is one of our favorite kind of dipping sauce. Is it possible to make this without the fish sauce and using a substitute? I really want to make some at home.

Thanks Sandhya! You can substitute light soy sauce for the fish sauce and it would still taste great! 🙂

We don't have Vietnamese restaurants here in Italy! But I remember this sauce from a restaurant I went to in London. Definitely want to make it myself. I think it would be fabulous with prawns!

Hi Jamie!
I had previously tried your hoisin and peanut dipping sauces, and was looking forward to giving this one a go too. We eat a lot of Vietnamese food at home, and are always looking for new dishes to try. This dipping sauce was a real success. We served it with some grilled prawns, but I really believe the opportunities are endless!
Love the pop of colour from the shredded carrot. Thanks for another great recipe!
Mona
Yum!! I tried your hoisin dipping sauce a couple of weeks ago, and this was next on the "to try" list - and so glad I did. We made some spring rolls, and this was a really lovely sauce to dip them in. The flavours are perfectly balanced.

Thanks Mona! I'm so glad you like this Vietnamese dipping sauce!
