How To Select, Store, and Cook Squid
What others are reading
To ensure safe consumption and the best culinary outcomes, follow these tips for choosing, storing, and preparing squid:
Selection Tips
- Freshness: For fresh squid, look for firm, moist flesh with a clean, ocean-like smell. The skin should be glossy, and the eyes clear, not cloudy or sunken.
- Color: The body should appear creamy white or lightly pinkish. Avoid any that are yellowed or display a sour odor.
- Frozen Option: Frozen squid often retains quality and is a convenient alternative to fresh squid.
Storage Guidelines
- Store fresh squid in the refrigerator and use it within one to two days.
- If uncleaned, keep the squid in its original packaging until ready to use to maintain freshness and prevent odors.
- Frozen squid should be kept in the freezer and can last up to six months.
- Thaw frozen squid overnight in the refrigerator or under running cold water before cooking.
Cleaning and Preparation
- Remove the head, innards, cartilage (quill), and skin before cooking.
- Rinse thoroughly under cold water.
- Separate the tentacles and body; both parts are edible.
Cooking Tips
- Squid becomes tough with prolonged cooking due to the composition of its proteins. For a tender texture, cook very quickly at high heat (grilled, sautéed, deep-fried) or braise slowly over low heat for an extended period.
- Popular methods include stir-frying, grilling, stewing, boiling, and deep-frying (as in calamari rings).
- Marinating squid in acidic ingredients (like lemon juice or vinegar) before cooking can enhance tenderness and flavor.
Safety Note:
Always ensure squid is cooked through to minimize the risk of foodborne illness.
