Shrimp and sweet potato sticks are fried in crispy batter. Banh tom makes a perfect appetizer.
What is Bánh Tôm?
Bánh Tôm is popular street food in Hanoi, Vietnam. It is also known as the West Lake fried shrimp cake. There are several restaurants along the West lake that serve banh tom. Whole shrimp and sweet potato sticks are fried in a batter until crispy. Banh tom is usually served with veggies such as lettuce and nuoc mam cham sauce.
How to make banh tom
1. You can leave the shell and tail on or you can remove the shell and leave the tail on. Either way, you want to devein the shrimp. If you leave the shell on, you can use a kitchen shear to cut through the shell on the back to remove the vein. Mix the shrimp with salt, garlic powder, ground white pepper and cornstarch. Set it aside while you prepare other things
2. Peel and cut the sweet potato on a bias into 1/4-inch thick rounds and then stack 4-5 rounds and cut into about 1/4-inch wide and about 3-4 inches long
3. Soak these potatoes in water. Add salt and vinegar. Let them soak for 30 minutes. Drain off the water and rinse the sweet potato with the salt and then pat them dry with an absorbent paper towel and set aside
4. Combine rice flour, all-purpose flour, cornstarch, salt, turmeric powder, baking powder, and sugar in a large mixing bowl
5. Add the water and whisk until you get a runny batter with no lumps. Cover and let the batter rests for 15 minutes
6. Preheat cooking oil over medium heat, about 2 inches high. You want to make sure there’s enough oil to get a good result. When you put a skewer in, there will be lots of bubbles around it or you can drizzle a bit of the batter and it will sizzle. The oil is ready
7. Put about 10-15 sweet potato sticks in the batter
8. Then scoop them up with a spoon and gently lower into the oil to let them fry for about 1 minute
9. Then dip a piece of shrimp in the batter and put on top of the sweet potato
10. Let it fry for about 4-5 minutes or until the shrimp turn pink and crispy
11. Remove from the oil and put on an absorbent paper towel. Continue with the rest of the batter, sweet potato sticks and shrimp
12. Once you are done frying all of them, bring the oil back to hot. Remove crumbs in the oil if any. Start from the first one that you fried and put it back into the oil and let it fry for about 1 minute or less. This round will be quick. We just want to crisp the fritter up. Fry until they are golden brown and crispy. Remove and put on absorbent paper towel. Keep them on a cooling rack in the oven at 200 F (93 C) to keep them warm and crispy when you fry the rest
13. Serve them while they are warm and crispy with some lettuce and fresh herbs like mints, cilantro leaves and nuoc mam cham sauce. Alternatively, you can also serve with store-bought sweet chili sauce or any chili sauce of your choice if you prefer
Important tips
1. Pat the shrimp dry before adding marinade so they stick to the shrimp
2. Cut the sweet potato sticks as evenly in size as possible so they cook at the same time
3. Soak the sweet potato sticks in a salt water to help crisp them up. The salt helps to draw out moisture from the sweet potatoes, making them crispier when you fry them
4. Double frying will give you very crispy fritters. Make sure you allow the fritter to cool down a bit before the second frying
