Purple Sweet Potato Rice Cooker Cake

Nutritional Value

1. High-Quality Protein

  • Eggs are an excellent source of protein, providing the body with various essential amino acids. They are easily digested and absorbed, which can help enhance physical strength.

2. Anti-Cancer Properties

  • The vitamin A in sweet potatoes can inhibit the binding of carcinogens to DNA, promoting the apoptosis of cells in the early stages of cancer, thereby helping to control cancer [1].
  • Sweet potatoes are rich in β-carotene, which can neutralize toxins and eliminate free radicals that damage cells, thereby fighting against cancer [2].
  • The ganglioside (40mg/100g) in sweet potatoes, which are a type of lipid in the mucilage component, can effectively inhibit the growth of cancer cells [3].

3. Detoxification

  • Sweet potatoes are high in dietary fiber, which can promote intestinal peristalsis and facilitate smooth bowel movements, reducing the contact between the intestinal wall, feces, and harmful substances, allowing them to be expelled from the body along with carcinogenic substances [4].

4. Metabolism Promotion

  • Milk is rich in B vitamins, which can promote the metabolism of carbohydrates, fats, and proteins, helping to convert them into energy. It is suitable for those who are malnourished and physically weak due to their treatment.

Note: Milk should be avoided by those with gastrointestinal discomfort or those who have just undergone gastrointestinal surgery. Milk should not be consumed within one hour before or after taking medications.

Ingredients

  • 2-3 medium-sized purple sweet potatoes 
  • Milk 
  • 2 Eggs

Directions

1. Wash the purple sweet potatoes and peel them. Slice them as thinly as possible.

2. Place the sliced sweet potatoes in a steamer basket and steam for 20 minutes until they become soft.

3. Mash the steamed sweet potatoes and set them aside.

4. Add a small amount of milk to the mashed sweet potatoes. 

5. Beat 2 eggs separately and mix them with the mashed sweet potatoes until it forms a cheesecake-like consistency.

6. Lightly grease the rice cooker pot with some cooking oil to prevent sticking.

7. Pour the mixture of mashed sweet potatoes directly into the rice cooker pot.

8. Gently tap the pot to remove any air bubbles. Set the rice cooker to the cooking mode, approximately 30 minutes. (Cooking time and temperature may vary depending on the brand of rice cooker.)

9. Once it cools down, remove the cake from the rice cooker pot, slice, and enjoy.

**  If you are sensitive to milk, you can omit it. Adding milk will make the texture smoother and add some nutritional value.
