How To Cook Seafood

: 5 Common Overcooking Mistakes That Ruin Texture

Quick Summary

How to cook seafood is a genuine question, as seafood cooks more quickly than mutton or chicken. Understanding the characteristics of seafood that react uniquely to heat will help avoid rubbery shellfish, dried fish, and separated curries. This will ensure the preservation of moisture, taste, and texture.

Deep Dive

The different types of seafood are distinct from red meat because they don’t have the same amount of connective tissue, which means they need to be cooked perfectly. It mainly depends on the type of seafood. White fish breaks down into flakes, prawns turn opaque and firm, while squid needs to be cooked either very briefly or for a long time. Thus, proper timing is the key to success.

How To Cook Seafood: A Culinary Art And Not Just a Technique

The reason is that seafood leaves very little room for error; therefore, many cooks say it is one of the most complicated products to learn. While tough cuts of meat can withstand longer cooking times, different types of seafood can go from their ideal taste and texture to dry or rubbery. It is important to understand the unique characteristics of each type to master seafood cooking.

The Truth About Overcooking Seafood: 5 Reasons Your Dish Falls Apart

1. You're Treating Every Seafood the Same

A critical error is to believe that all types of seafood, including white fish, prawns, squid, scallops, and snails, behave the same when cooking. For instance, delicate white fish like cod cook very quickly, while prawns only become opaque after a few minutes. On the other hand, squid is notorious for its narrow cooking time window. The same can be said about marine snails - they have to be cooked for a long time before they become tender. Using the same cooking times for all types of seafood will result in at least one of them being overcooked. 

2. High Heat for Too Long

A common error many home cooks make is to keep cooking seafood because the meat "does not look properly cooked". However, seafood continues cooking even after being removed from the heat due to residual heat. As a result, prawns become too rubbery, and white fish dries out; sashimi loses its silkiness once cooked. So, remove the seafood once it is almost cooked, and let the residual heat finish the job. 

3. Fish Falling Apart in Curries

White fish, such as cod, basa, haddock, and snapper, can easily crumble when cooked in simmering gravy. This may happen due to stirring the fish multiple times or keeping it in the curry for too long. The right thing would be to cook the gravy first and add the fish towards the end, with minimal stirring. Certain fish are much firmer and tend to survive better in sauces.

4. Rubbery Prawns and Chewy Squid

When prawns have a rubbery texture, that almost always means they have been overcooked. Prawns which have been cooked properly are firm and opaque but not tough. Squid, on the other hand, must be cooked either very quickly at high heat or for a long time at low heat; if cooked at an intermediate temperature, it will turn out rubbery. 

5. Starting With Poorly Prepared Seafood

Cooking cannot fix seafood that has not been properly thawed or dried before cooking. Excess moisture on the frozen seafood prevents it from browning, making it steam instead of fry. Whenever seafood is frozen, it should be thawed properly either in the fridge or in running cold water before cooking.
