When storing rice, the more airtight your container is, the better it will retain its texture. But after a few days in the fridge, there's no way around it: your rice will start to dry out. The first reheating method led me to the stove top, using the least amount of added liquid and a wide, flat skillet with enough surface area for even heating.
Remove rice leftovers from the fridge and let it sit for 10-30 minutes, or until it reaches room temperature. Be sure to only do this with rice you want to consume immediately, as cooling and reheating rice too many times can promote bacteria growth.
Start by placing the leftover rice in a large skillet, over low heat, and add a splash of water or vegetable stock. Cover with a well-fitting lid and cook for 3 - 5 minutes, stirring occasionally to break up any clumps. This method involving gentle heat and an introduction of moisture will result in light, fluffy rice, just as it was the day before.
