This small group of aquatic creatures comprises cuttlefish, squid and octopus, none of them very attractive except when presented in the pot. But their taste is so delicious that you are unlikely to be put off by their looks. Like all fish, they should be fresh not frozen, although frozen have the advantage that their flesh is relaxed, making them cook more quickly. But they are less tasty. If you are at the seaside and lucky enough to have the chance of buying some squid or cuttlefish, or an octopus, that have just been caught, you must leave them in the fridge for about 2 days to relax their flesh before you cook them. Italians love to eat these strange-looking fish and have created many recipes around them
