Rinse split peas and soak in water for at least 3 hours or overnight.

Drain the soaked peas.

Puree the peas with garlic, curry powder, salt, and serrano pepper in a food processor or blender.

Sift baking powder and flour into a bowl.

Mix the pea puree into the flour mixture, adding more flour if needed to create a stiff batter.

Heat oil to 375°F (190°C) in a deep fryer or heavy skillet.

Drop teaspoonfuls of batter into the hot oil in batches.

Fry until golden brown, turning as needed.

Drain on paper towels and sprinkle with salt if desired.
