Chinese yam adds a delicate sweetness and slight viscosity to a nourishing rice porridge. This healthy, vegetarian family congee is prized in Traditional Chinese Medicine for supporting digestion and energy.
Rinse the rice under cold running water until the water runs clear, then drain thoroughly.
Peel the Chinese yam (wearing gloves to avoid stickiness), slice into thin matchsticks, and set aside. Peel and dice the carrot; slice the scallions, reserving some green parts for garnish.
In a large heavy pot, combine the rinsed rice and water. Bring to a boil over medium-high heat, stirring occasionally to prevent sticking.
Once boiling, reduce the heat to low and simmer uncovered for 30 minutes, stirring every 5 minutes to keep the rice from sticking to the pot bottom.
Add the Chinese yam and diced carrot to the pot. Continue simmering on low heat for 20 more minutes, until congee is creamy and the yam is tender.
Season with salt and white pepper. Stir well and cook for another 3 minutes; taste and adjust seasoning as needed.
Turn off heat. Swirl in toasted sesame oil, ladle into bowls, and garnish with scallion greens before serving.
