Larger octopus tend to be tough — tenderise them before cooking by pounding with a mallet or rolling pin. Some cooks claim that freezing octopus improves the tenderness, and in some countries it is not uncommon to see octopus being tenderised in a cement mixer. Your octopus is sufficiently tenderised when it no longer feels bouncy.
Small or baby octopus are more tender and don’t need beating or blanching before cooking. Baby octopus are perfect for barbecuing.
Octopus can be grilled, poached, sautéed, fried or steamed. Slow cooking over low heat makes the flesh more tender. Larger octopus should be simmered gently for about 60—90 minutes.
Fresh octopus will keep for 1–2 days in the fridge and for about 3 months in the freezer.
