Shrimp Cakes (Banh Tom)
I first encountered bánh tôm on the breezy streets surrounding Hanoi’s West Lake, where vendors fry these golden discs until they sing. At its heart, this snack is a quiet triumph of contrast: the earthy, caramelizing sweetness of thinly sliced sweet potato meeting the bright, oceanic snap of whole shrimp, all bound by a whisper-light rice flour batter. It matters precisely because it refuses to hide behind heavy sauces or complex spice blends; the ingredients must speak for themselves. Yet, when you walk into a supermarket and pick up a box of frozen shrimp fritters, you’re usually paying seven or eight dollars for a pale imitation. Those mass-produced discs are packed with cheap extenders, artificial binders, and sodium-heavy flavor pastes that turn the shrimp rubbery and the crust greasy. The from-scratch version costs a fraction of that, but the real victory is in the texture and the honest, clean flavor. The pitfalls are entirely avoidable if you respect the process. Too often, home cooks slice the sweet potato too thickly, which guarantees a raw center, or they drown the batter in water, leading to a soggy, oil-soaked mess. Overcrowding the wok drops the temperature instantly, turning what should be a crisp, lacy shell into a heavy, leaden disc. I always insist on resting the batter briefly to let the rice flour hydrate fully, keeping the oil at a steady three hundred fifty degrees, and frying in small, uncrowded batches. When done right, these cakes shatter on the bite and leave you reaching for another before the first has even cooled.

Shop-bought frozen shrimp cakes cost around eight to ten dollars per box and are typically dense with breadcrumbs, stabilizers, and stale oil flavor. This beginner version replaces that processed compromise with a straightforward from-scratch method that prioritizes confidence over perfection. We skip precise julienning by using a standard box grater for the sweet potato, and rely on a forgiving rice flour and cornstarch batter that binds easily without eggs or heavy binders. Instead of deep-frying, we shallow-fry in a heavy skillet to control heat, minimize splatter, and simplify cleanup. Watch your oil temperature closely: aim for a steady, medium sizzle. If the edges darken too quickly, reduce the heat immediately to let the sweet potato steam through without burning the crust. Keep each patty roughly the same thickness and press gently so the cakes hold together when flipped. The result is a light, naturally sweet fritter with a crisp exterior and tender interior, proving that a few simple techniques and real ingredients easily outperform the freezer aisle.
Equipment
- Heavy-bottomed skillet— Cast iron or stainless steel works best for heat retention
- Box grater— Use the medium holes
- Wire cooling rack— Prevents sogginess after frying
Method
- 1
Peel two medium sweet potatoes and coarsely grate them using a box grater.
Squeeze excess moisture out with a clean kitchen towel to prevent a soggy crust.
grating~ 5 min - 2
Whisk together rice flour, cornstarch, cold water, and a pinch of salt in a large bowl until completely smooth.
The batter should coat the back of a spoon like heavy cream.
whisking~ 2 min - 3
Fold the grated sweet potato and finely chopped scallions into the batter, then let the mixture rest for ten minutes.
Resting hydrates the starch so the cakes bind without falling apart during frying.
resting~ 10 min - 4
Divide the mixture into eight equal portions, flatten each into a three-inch round, and gently press two raw shrimp onto the top of each patty.
Press firmly so the shrimp adheres securely before hitting the oil.
shaping~ 4 min - 5
Pour enough neutral oil into a heavy skillet to cover the bottom by half an inch and heat over medium until a wooden chopstick placed at the edge releases steady bubbles.
If the oil smokes, remove from heat immediately; too much heat will burn the exterior before the potato cooks.
temperature_testing~ 3 minTricky bit - 6
Carefully lower the patties into the hot oil, fry for three minutes until the edges lift, flip gently, and cook until golden brown on both sides before transferring to a wire rack.
Do not crowd the pan; cook in batches to maintain consistent oil temperature.
shallow_frying~ 8 minTricky bit
Cooking from frozen
Reheat directly from frozen in a 375°F oven or air fryer for 8–10 minutes to restore crispness.
