Soaking Fish in Rice Water: A Simple Trick to Make Fish Tastier and Twice as Nutritious

A highly effective traditional tip — soaking fish in rice water — not only removes the fishy odor but also makes the flesh firmer, more flavorful, and helps retain more nutrients.

In Vietnamese kitchens, fish is a familiar and nutritious dish that’s easy to prepare. However, many people struggle with fish that smells fishy, has a mushy texture, or loses nutrients during cooking.

1. Why You Should Soak Fish in Rice Water

When you soak fish in rice water, the natural components in the rice water work wonders:

• Neutralizes fishy odors: Fish contains trimethylamine, the compound responsible for its fishy smell. The mild alkalinity of rice water helps neutralize and remove this odor.

• Removes slime and dirt: Especially useful for freshwater or river fish, rice water effectively cleans away the slimy layer and impurities on the skin.

• Firms up the fish texture: The starch in rice water lightly coats the surface of the fish, helping it stay firm and intact when cooked.

• Preserves natural nutrients: Proper soaking prevents the loss of valuable protein and healthy fats during the cooking process.

2. How to Soak Fish in Rice Water

Step 1: Prepare the rice water

• Use the second rinse from washing clean rice — avoid the first rinse, which may still contain dirt or debris.

• Use enough water to fully submerge the fish.

Step 2: Soak the fish

• Rinse the fish briefly with clean water.

• Soak it in rice water for 10–15 minutes.

• Then rinse again with cold water and pat dry before seasoning or cooking.

Tips:

• Do not soak the fish for too long, as it may lose its freshness.

• For fish with a strong odor (like catfish or basa), you can add a few slices of ginger or a pinch of salt to the rice water to enhance deodorizing effects.

3. Extra Tips to Make Fish Tastier and More Nutritious

• Fried fish: After soaking, pat the fish dry and coat lightly with flour before frying. The rice starch helps create a golden, crispy crust while keeping the inside moist.

• Braised fish: Fish soaked in rice water absorbs seasonings more evenly, resulting in a tender but not mushy texture.

• Steamed or cooked in soup: The fish will have a naturally sweet flavor, free from any fishy smell, and pairs wonderfully with vegetables.

Fish is a rich source of omega-3 fatty acids, protein, and natural vitamin D — all of which support heart health, brain function, and skin vitality. Soaking fish in rice water helps remove impurities and excess fat, making it cleaner and more nutritious — especially beneficial for the elderly and children.

Soaking fish in rice water is a simple yet powerful kitchen secret that enhances flavor, improves texture, and boosts nutritional value. With just one readily available ingredient, you can turn everyday meals into wholesome, delicious dishes for the whole family.
