Cleaning the squid: Rinse the squid thoroughly under cold water. Remove all inedible parts such as the outer skin and insides. Once the squid are whole, cut them into slices about 1 cm thick. If you are using pre-sliced squid, make sure they are uniform in size to ensure even cooking.
Prepare the marinade: Add the baking soda to the mineral water with lemon juice or sparkling water. Mix well until the baking soda is completely dissolved. This solution helps to tenderize the squid and ensures perfect crispiness when frying.
Soak the squid: Place the squid in the prepared solution and soak for 15-30 minutes. This step is important to improve the texture and flavour of the squid and contribute to the crispiness.
