Prepare the Lemon Aioli
In a small bowl, combine the mayonnaise, lemon juice, lemon zest, and minced garlic. Stir until well mixed.
Season with salt and pepper to taste. If you prefer a stronger lemon flavor, add more zest or juice. Set aside in the fridge until ready to serve.
Batter the Calamari
In a shallow dish, combine the flour, paprika, garlic powder, salt, black pepper, and cayenne pepper.
Toss the squid rings into the seasoned flour mixture, making sure each piece is evenly coated. Shake off any excess flour.
Fry the Calamari
Heat vegetable oil in a deep frying pan or deep fryer to 375°F (190°C). You want enough oil to fully submerge the calamari.
Fry the calamari in small batches, being careful not to overcrowd the pan. Fry for about 2-3 minutes or until golden brown and crispy.
Use tongs or a slotted spoon to remove the calamari and transfer to a paper towel-lined plate to drain any excess oil.
Serve
Arrange the crispy fried calamari on a serving platter. Serve with the lemon aioli for dipping. Optionally, garnish with extra lemon wedges for added citrus flavor.
