To prepare the prawn fritters, you'll first need to prepare your ingredients. Heat 2 tablespoons of vegetable oil in a large skillet over medium-high heat. Add 2 tbsp. of minced garlic to the oil and cook, stirring frequently, until the garlic is fragrant, 2 to 3 minutes. Stir in 1 cup of chopped thai basil, 1 teaspoon each ground cumin and coriander, and 2 teaspoons each kosher salt and ground black pepper. Cook the mixture for 2 minutes, then stir in 2 cups of shredded scallions. Pour the batter into the skillet and fry until golden brown, 3 to 4 minutes on each side. Remove from the heat and set aside to cool.
