Start by Savoring the Soup

Begin by tasting the soup.
In Thailand, it’s customary to use a stainless steel spoon to enjoy it.
Enjoy the Sen Lek Noodles

After savoring the soup, enjoy the noodles.
In Thailand, slurping noodles is considered impolite. Use a spoon to take bites of the noodles or cut them into smaller portions with chopsticks before eating.
Adjust the Flavor with Thai Condiments

At Thai street stalls, you’ll always find a condiment set called “Kruang Prung” on the table. Starting from the top right and going clockwise: vinegar, fish sauce (nam pla), sugar, and chili powder. These four are the basics. Use them to adjust the flavor to your liking.


Start by adding “nam pla,” the staple Thai condiment. Nam pla is fish sauce, packed with umami from fermented fish. Its unique flavor makes it perfect for enhancing your dish.


If you prefer more heat, add some chili powder.

If you’re looking for a more refreshing taste, adding vinegar is a great option. The chili pepper called “Prik Chi Fa” in the vinegar is not spicy, so even those sensitive to heat can enjoy it without worry.
You Can Switch to Chinese Noodles

Sen Lek Nam is made with rice noodles called sen lek, but at Krung Siam, you can switch to Chinese-style egg noodles (sen mee) if you prefer. That version is called “Sen Mee Nam.” Just ask the staff when placing your order.

Each time you adjust the flavor, you can bring out new depths of taste in your Sen Lek Nam.
Next time you visit a Thai restaurant, why not enjoy Sen Lek Nam the Thai way, with your own flavor twists?
