Preparing your own baby food is less expensive than buying processed baby food at the supermarket. An apple cost about 25 cents in 2010, while a 2.25-ounce jar of baby-food applesauce cost $1. Applesauce is one of the first "people" foods for many babies. Use it as a natural sweetener in baby's cereal. Of course, follow the advice of your pediatrician when adding any new foods to baby's diet.
Select apples that are firm and unblemished. Consider organic apples. Regular apples are often contaminated with pesticides, according to the Environmental Working Group's Food News website.
Wash your hands, the knife, cutting board, saucepan, glass container and lid and spoon with hot soapy water. Sanitation is important when you are preparing baby food.
Wash the apples. Peel, core and remove the seeds. Thinly slice.
Put the apples slices into a saucepan and barely cover with water. The less water the better, because the nutrients stay in the apples instead of leaching into the water, says the University of Maine Cooperative Extension.
Bring the apples and the liquid to a boil. Lower the heat and simmer until the apples are soft. That probably won't take more than 10 minutes.
Drain the apples.
Put in a food processor, blender or baby food grinder and process until the apples are almost liquid. Add a teaspoon of baby apple juice if the applesauce is too thick.
Store in the applesauce in a glass jar in the refrigerator for up to several days. Remove a portion when you want to feed the baby. Do not return the uneaten applesauce to the jar or store it for later. The applesauce may be frozen in ice cube trays that have been sanitized with boiling water. One cube is a baby-size portion.
