If you have cooked rice that is still crunchy, don't worry; there are a few simple methods you can try to fix it and make it soft and fully cooked. Here's what you can do:
Add more water and continue cooking: The easiest way to fix crunchy rice is to add more water or broth to the pot and continue cooking it. Place the rice back on the stove over low heat, add the liquid (about 1/4 to 1/2 cup), cover the pot with a lid, and let it simmer until the rice absorbs the liquid and becomes softer. Check it occasionally to prevent burning and stir gently if needed.
Use a microwave: If you prefer, you can transfer the crunchy rice to a microwave-safe bowl, add some water or broth (about 1/4 to 1/2 cup), cover the bowl with a microwave-safe lid or microwave-safe plastic wrap with a small vent, and microwave it on medium power in short intervals (e.g., 1 minute) until the rice becomes soft and fully cooked.
Steam the rice: Another method is to transfer the crunchy rice to a heatproof colander or steamer basket, place it over a pot of boiling water, and steam the rice until it becomes soft. Make sure to cover the pot with a lid or foil to trap the steam and cook the rice evenly.
Use a rice cooker: If you have a rice cooker, you can transfer the crunchy rice to the rice cooker, add more water or broth, and let it cook again using the regular rice cooking settings.
Before trying any of these methods, make sure to taste the rice to determine how crunchy it is. If the rice is severely undercooked and hard, it may be challenging to salvage it completely. However, these methods should work well for slightly undercooked rice. Remember, it's essential to use the appropriate amount of liquid and not overcook the rice, as it can become mushy if cooked for too long.
