To make tempura, mix flour, cornstarch, baking powder, and curry powder in a bowl. Dredge the shrimp in this dry mix, shaking any excess back into the bowl, and add seltzer to the tempura in a stream while whisking constantly to make it into batter. Season with salt and pepper.

Heat canola oil to 375 degrees F in a deep-fryer, or according to the manufacturer's instructions for similar foods.

Thread the dusted shrimp onto skewers, approximately 4 to a skewer. Pour the tempura batter into a glass pie plate, dip each skewer of shrimp into the tempura batter, and add to the deep- fryer basket. Fry until golden brown. Drain on paper toweling and serve warm.
