FAQs

1. Can I substitute the crab meat with another seafood?

While crab is traditional, you can try shrimp or even imitation crab meat for a similar texture. However, the flavor profile will differ significantly.

2. What if I don't have mắm tôm (fermented shrimp paste)?

Mắm tôm is key to the authentic flavor, but if you can't find it, you can try adding a little fish sauce and shrimp paste (from a tube or jar). The flavor won't be exactly the same, but it'll still be tasty.
