Heat 2 inches of oil in a large pot over medium heat to 165 degrees F.
Set up your assembly line. In one shallow dish whisk together milk and egg. In another shallow dish, combine flour, cornstarch, granulated garlic, salt and pepper.
Dip the calamari rings into the egg was. Gently let the excess drip off.
Dredge the calamari rings in the seasoned flour mixture. Shake off any excess.
Fry calamari, in batches if necessary to avoid over crowding the pan, for 2 1/2 minutes. Use a slotted spoon to transfer to a paper towel lined plate. Sprinkle with salt.
To make the Pesto Aioli Sauce whisk together all ingredients.
Notes
I have found that frying the rings at 165 degrees for 2 1/2 minutes to be the best combo for tender calamari.Also be sure not to crowd the pan when frying. I usually fry in batches to avoid this. I also recommend allowing the oil to come back up to 165 degrees in between batches to ensure you can cook at the proper temperature. Use a thermometer to check the oil temperature.
