To cook rice in a pot on the stove, follow these steps for perfect fluffy rice:

1. Rinse the rice under cold water until the water runs clear to remove excess starch.
2. Use a ratio of about 2 parts water to 1 part rice (for example, 2 cups water for 1 cup rice).
3. Add the rinsed rice and water to a pot, add a pinch of salt if desired, and bring it to a boil over medium-high heat.
4. Once boiling, reduce the heat to low and cover the pot with a tight-fitting lid.
5. Let it simmer gently for about 15 to 18 minutes without lifting the lid or stirring.
6. After cooking, turn off the heat and let the rice rest, covered, for another 10 minutes to steam.
7. Fluff the rice with a fork before serving.

This method results in tender, fluffy rice and works well for long-grain white rice. Adjust water ratios slightly for firmer or softer rice or different rice varieties. Avoid stirring while cooking to prevent gummy rice.
