What is the difference between Mam Ruot and Mam Tom?
Mam Tom is made from shrimp and comes from Northern Viet Nam , Mam Ruot is from South and Central Viet Nam. Mam Ruot is made from small shrimps. It takes at least 5-6 months to make so the smell is stronger and salter. :-)
Add sugar and 1-2 teaspoons of water, a few drop of lemon and mix them up
Depending on how much Mam Ruot you have in a bowl, add sugar and lemon as desired (for my sauce, I added 4-5 teaspoon of Mam Ruot and 2-3 tablespoons of sugar)
Mam Ruot is really salty so it's up to you to adjust the sugar and lemon accordingly.
