Over 70% of the Earth’s surface is covered by seawater, which makes up the oceans and seas. Seawater is made up of 96.5 percent water, 2.5 percent salts, and trace amounts of dissolved inorganic and organic compounds, particles, and a few atmospheric gases.

So if you are in search of an answer to whether you can cook with seawater, then you need not worry as we are going to answer all your questions.

So without much ado, let’s dive in and figure out more about it. 

Can you cook with seawater?

Yes, You can cook with seawater. Crab boils, lobster cook-offs, and other fresh-caught seafood are all popular with seawater cookery. 

Seawater cooking is tempting because you can just drag in a bucketful from the ocean without having to cart heavy jugs from the home, and coastal grills make seawater cooking appealing because you can just pull in a bucketful from the ocean without having to cart heavy jugs from the house.

Foods to cook using seawater

Crab, lobster, and clams in their shells are the greatest candidates for seawater cooking. Crawfish and other edible freshwater crustaceans are also excellent choices. The natural salts bring out the flavor of the meat, but the shells keep it from being excessively salty. This method of seawater cooking is ideal for camping.

Because many youngsters are sensitive about shellfish, you might want to bring along a few hot dogs to roast as well if you have picky eaters in the family. To complete the dinner, serve it with a quick and easy salad topped with raw veggies and a creamy dressing.

Why do we mix seawater and freshwater?

To prepare other products that can absorb too much salt from pure seawater cooking, combine a small amount of boiling seawater with fresh water. For example, one part seawater to three or four parts freshwater can be used to boil potatoes.

Use no more than a couple of teaspoons of seawater to season pasta, rice, and other similar items; because seawater must be cooked, it might be an unpleasant substitute for table salt. If you cut it with unsalted liquids, seawater makes a great seafood soup foundation.

How to use seawater properly?

To eliminate any biological creatures that can pollute the water, boil any unregulated water supply, even seawater. The boiling point of water is 212 degrees Fahrenheit, and a few minutes at 185 degrees is enough to kill any organisms, so you can be sure the water is safe by waiting for it to come to a full boil.

Boiling, on the other hand, does not remove chemical pollution, which is why you should be on the lookout for warning indications. If your children are old enough to grasp the dangers, have them keep an eye on the water pot while you finish the remainder of the meal, as you must wait for the water to boil before adding your food.

A simple recipe of cooking rice with seawater


  • 1 cup white rice (for two people)
  • A little amount of olive oil
  • Enough seawater to cover the rice


Thoroughly wash the rice until the water runs clear. Put it in a pot and cover it with seawater. Add a dash of olive oil and cook, covered, on low heat. Turn off the stove when it’s halfway done and the rice has developed a “belly,” and cover it to finish cooking on its own.

This is a really easy dish that will hopefully demonstrate how to cook with seawater. What I’ve discovered is that substituting seawater for all liquids gives me the flavor I desire. In some circumstances, such as tomato sauce, I do need to adjust the flavor with Himalayan salt. However, for foods like potato salad, rice, and soup, plain seawater will suffice.

The taste isn’t quite the same as table salt; it’s a touch more bitter, which is likely due to the magnesium and potassium salts in it.

Is it possible to survive by drinking seawater?

Humans are poisoned by seawater because their bodies are unable to eliminate the salt it contains. The kidneys generally eliminate excess salt by producing urine, but freshwater is required for the kidneys to function effectively.
