- Preheat the oil in a deep fryer to 350°F (180°C). Line a baking sheet with paper towels.
- In a bowl, whisk together the corn masa flour, tapioca flour, baking powder, salt and spices. Stir in the eggs and water. Add the vegetables and tuna. Combine until smooth. Set aside.
- With a 1-tbsp (15 ml) ice cream scoop, gently drop about 10 balls of batter into the hot oil. Watch out for splattering. Fry for 4 minutes or until the fritters are golden brown, turning halfway through cooking. Drain on the paper towels.
- Serve hot with the lime wedges.
Instant corn masa flour is made from ground dried masa: corn softened with slaked lime or wood ash and turned into dough. It can be found in most supermarkets or Latin American grocery stores.
