If your rice becomes too salty, there are a few methods you can use to help reduce the saltiness. Here are some steps you can take to salvage the rice:
Rinse the rice: Place the cooked rice in a fine-mesh sieve or colander and rinse it under cold water. This will help remove some of the excess salt on the surface of the rice grains.
Add unsalted cooked rice: If you have additional plain, unsalted cooked rice on hand, you can mix it with the salty rice. Combining the two will help dilute the overall saltiness.
Boil in unsalted water: Another method is to boil a pot of unsalted water separately and then add the salty rice to it. Allow the rice to cook in the unsalted water for a few minutes, stirring occasionally. The rice will absorb some of the plain water, which can help reduce the salt concentration.
Use a potato: You can also try adding a peeled and halved potato to the pot of salty rice. The potato will absorb some of the salt during cooking. Remove the potato halves before serving the rice.
Add acid or sweetness: If the rice still tastes too salty after trying the above methods, you can try balancing the flavor by adding a small amount of acid or sweetness. For acidity, a squeeze of lemon juice or a splash of vinegar can help cut through the saltiness. For sweetness, a teaspoon of sugar or a drizzle of honey can help counterbalance the saltiness.
Remember that these methods may help reduce the saltiness to some extent, but they may not completely eliminate it. It's always a good idea to taste and adjust as you go to achieve the desired flavor balance.
