In a food processor, mix fish, garlic, and scallions.
Add the lemongrass, fish sauce, sugar, black pepper, chili, prahok, and 1 tablespoon oil to this mixture.
Take about a tablespoon of mix and form a small patty and repeat this process.
Place the patties on a sheet of parchment paper.
Heat a frying pan or wok over medium-high heat.
When the pan is hot, add the remaining oil and fry the fish patties until they are cooked and browned on both sides.
Serve with steamed white rice or as an appetizer.
Enjoy!
