- 2 cups cooked spinach
- 1 cup all-purpose flour
- 1 cup chilled sparkling water
- 2 eggs
- 1/2 cup grated Parmesan cheese
- 1 teaspoon baking powder
- 1 teaspoon chopped garlic
- 1/4 teaspoon white vinegar, or to taste
- salt and ground black pepper to taste
- oil for frying
- Combine spinach, flour, sparkling water, eggs, Parmesan cheese, baking powder, garlic, vinegar, salt, and black pepper together in a bowl until batter is evenly combined.
- Heat enough oil to cover the bottom of a large skillet over medium heat. Spoon batter into the hot oil, keeping about 1 inch between each croquette. Cook until golden brown, about 90 seconds per side. Repeat with remaining batter.
