Tortillitas de camarones are shrimp fritters from the province of Cádiz in Andalusia, Spain.
They are made with a batter of wheat flour, chickpea flour, water, onion (alternatively shallot or scallion), parsley, shrimp, salt and pepper.
The batter is then fried on both sides in a pan with plenty of olive oil.
In Andalusia the shrimp species Palaemon longirostris is typically used, for which camarón is the local name.
A different species of shelled shrimp can serve as a substitute, but without Palaemon longirostris the taste of the dish will be different.
