Rinse the Rice: Wash 1 cup of white rice thoroughly under cold water until the water runs completely clear, then drain it well.
Combine Ingredients: In a large, heavy-bottomed pot, combine the rinsed rice with 8 to 10 cups of your chosen liquid (broth or water) and add the smashed ginger.
Boil and Simmer: Place the pot over high heat and bring it to a rolling boil. Stir well to prevent sticking, then reduce the heat to the lowest setting.
Slow Cook: Cover the pot with the lid slightly ajar to let steam escape. Let it simmer gently for 60 to 90 minutes.
Stir for Creaminess: Stir the pot thoroughly every 15 minutes to help release the rice starches, giving the congee its signature smooth, velvety texture.
Garnish and Serve: Ladle the warm congee into bowls and finish with your favorite savory toppings like soy sauce, sesame oil, or green onions.
