1. Ask the staff at the Metro supermarket fish counter to clean the squid for you. Place them in a bowl and pour the vinegar over them. Mix well and cover the bowl. Set aside for 30 minutes or refrigerate for longer. Stir occasionally.
2. Pat the squid very dry with paper towels.
3. In a bowl, mix the flour, cornstarch, semolina, oregano, onion powder, garlic powder, saffron, and salt.
4. Pour the sunflower oil into a small deep pot and place it on the heat to warm up. Put the squid into the flour mixture and toss them so the flour coats everything.
5. Shake off the excess flour mixture and fry the calamari in small batches in the hot oil. Remove and place on a plate lined with paper towels. Serve the calamari with lemon wedges so everyone can add as much as they like.
