West Lake shrimp fritters (banh tom Ho Tay)
West Lake shrimp fritters are a famous Hanoi afternoon snack: strands of sweet potato bound in a turmeric-golden batter, topped with whole shrimp and fried until shatteringly crisp. They are served with fresh herbs and a sweet and sour fish sauce dip, and the mellow sweetness of the potato, the bright red shrimp and the crunchy crust make an unforgettable combination.

Ingredients
Frying batter
Sweet potato and shrimp
Sweet and sour fish sauce dip
Frying oil and herbs for serving
Instructions
Step 1
Mix 150 g all-purpose flour, 30 g rice flour, 2 g ground turmeric, 3 g baking powder and 2 g salt, then add 50 g egg and 200 g cold water, stir well and let the batter rest for about 20 minutes. Rice flour and cold water keep the crust crisp for longer, while turmeric gives the signature golden color. The batter is ready when it is about as thick as thinned condensed milk and coats the back of a spoon in a thin layer.
Step 2
Trim the antennae and legs from 250 g fresh shrimp but leave the shells on, rinse and drain them, then season with 5 g fish sauce and a pinch ground black pepper. Keeping the shells on makes the shrimp crunchy and turns them a beautiful red when fried, just like traditional shrimp fritters. The shrimp are ready when their surface is dry and they are evenly seasoned.
Step 3
Peel 300 g sweet potatoes, cut them into long matchstick strips, soak them in cold water for about ten minutes, then drain and pat them very dry. Soaking washes away some of the starchy sap, so the strands fry up crisp and do not clump together. The strands are ready when they separate easily, feel dry and no longer drip.
Step 4
Dissolve 30 g granulated sugar in 90 g warm water, then add 30 g fish sauce, 15 g lime juice and 5 g minced garlic and stir well. A balanced sweet and sour dip cuts through the richness of the fritters and brings out the flavor of the shrimp. The sauce is ready when it tastes evenly salty and sweet and the garlic floats on the surface.
Step 5
Heat to taste oil for deep-frying in a deep pan over medium heat to about 170°C. When the oil is hot enough, the fritters set their shape as soon as they go in instead of soaking up oil. The oil is ready when small bubbles fizz steadily around the tip of a wooden chopstick dipped into it.
Step 6
Mix a handful of sweet potato strands with a few spoonfuls of batter, spread it into a flat round on a flat ladle, set one or two shrimp on top, then lower the whole ladle into the oil, fry for about six minutes and flip the fritter once it releases from the ladle on its own. Frying on the ladle keeps the fritters round and helps the shrimp stick to the potato. They are done when both sides are deep golden, the shrimp are bright red and a light tap sounds crisp.
Step 7
Lift the fritters out and stand them on their edges on a rack to drain, cut them in halves or quarters and serve with to taste mixed fresh herbs and the sweet and sour dip. Eat them right away while hot, when the crust is at its crispiest and the shrimp at their most fragrant. The platter is just right when every piece is golden and crisp, with the red shrimp standing out against the potato.
Equipment
- Deep skillet
- Mixing bowl
- Whisk
- Thermometer
- Wire cooling rack
- Kitchen scale
Tips
- Yellow-fleshed sweet potatoes that are not too watery give crisper, sweeter strands, so avoid very floury varieties.
- Frying twice, first to cook them through and then over higher heat for one minute, keeps the fritters crisp for longer.
- For a true Hanoi touch, add a few slices of pickled green papaya and fresh chili to the dipping sauce.
Storage
Shrimp fritters are best eaten straight from the fryer. Leftovers keep in the fridge for one day; to serve, reheat them in the oven or an air fryer at 180°C for about five minutes until crisp again.
Common problems and how to fix them
- The fritters turn soft and greasy.
- The oil was not hot enough or the sweet potato strands were still wet. Pat the potato very dry and wait until the oil reaches temperature before adding the fritters.
- The fritters fall apart while frying.
- There was too little batter mixed with the potato to bind it. Add a bit more batter to each handful of potato and let the underside turn golden before flipping.
