Using unused rice flour to make baby food supplements is a smart approach. It not only makes full use of the ingredients, but also provides nutritious food for the baby. Here are some suggestions on how to use unused rice flour to make complementary foods that your baby likes:

1. Rice flour paste: Mix rice flour with an appropriate amount of water and stir evenly to form a thick paste. Place the rice flour paste in the microwave and heat for 30 seconds to 1 minute to soften. During the heating process, stir every 30 seconds to avoid burning the bottom.

2. Rice flour porridge: Add an appropriate amount of rice flour to the cooked porridge and stir evenly to mix the rice flour and porridge. Rice flour porridge can increase the consistency and taste of the porridge, and your baby will like it more.

3. Rice flour cake: Mix rice flour, pureed vegetables (such as carrots, spinach, pumpkin, etc.), eggs and water together and stir into a uniform paste. Brush a layer of oil on the pan with a brush, pour the paste into the pan, flatten it with a spatula, and fry until both sides are golden brown.

4. Rice flour pasta: Use rice flour instead of flour to make pasta, such as rice flour noodles, rice flour steamed buns, etc. Mix rice flour with appropriate amount of water and knead into dough. Simply roll out the dough and cut into thin strips or cubes, then steam or cook.

5. Rice flour puree: Cut the fruits (such as apples, bananas, pears, etc.) into small pieces, mix them with rice flour, and put them in a blender to form a puree. You can add an appropriate amount of water or milk according to your baby's taste and needs.

6. Rice noodles with minced meat: Boil or steam meat (such as chicken, pork, fish, etc.), remove the skin and bones, and then mix with rice noodles. Place in a blender and puree until smooth. You can add an appropriate amount of water or milk according to your baby's taste and needs.

These are just some simple ways to make rice flour supplements. You can innovate and adjust them according to your baby's taste and needs. During the preparation process, please ensure that the ingredients are fresh and avoid adding too much salt, sugar and other seasonings to maintain the light taste of the complementary food. Also, ensure that proper hygiene and safety measures are followed during the production process.
