Notes
Yield: 1 cup sweet potato puree, four ¼ cup serves
For a richer flavor you can bake the sweet potato in its skin on a baking sheet in the oven until tender, instead of cooking it with water on the stovetop.
Freeze portions of your sweet potato purée in ice cube trays or baby food trays.
Sweet potato purée is also a delicious side dish for a family meal, Once blended you can blend in a little butter or olive oil and season to taste with salt and pepper (please note that if you have salted your puree it is no longer appropriate as a first food for your baby.
Store your sweet potato puree in a clean airtight container or jar in the refrigerator for up to 4 days, or freeze for up to four months.
Sweet Potato: In New Zealand sweet potatoes are known as K?mara
Orange Sweet Potato: When making sweet potato baby food I like to use orange-fleshed sweet potato or k?mara as is less starch than other varieties of sweet potato and therefore blends well into a very smooth and velvety baby purée.
Select firm, well-shaped k?mara/sweet potato with clean smooth skin, no soft spots and or any obvious signs of decay or wrinkling.
