Root Vegetable Purée
One of the first combined purées I made for my daughter was steamed root vegetables blended until smooth. Once she had tried sweet potato, parsnip, butternut squash & carrot, I would blend them all together for a mixed root vegetable puree.
You can also add a measure of homemade vegetable stock, or chicken stock, for extra nutrition (boiling water is fine too if you don't have any homemade, or no salt added stock).
Quick tip ~
This also makes a great soup for yourself too, just add more stock and season to taste
As she got bigger, I would serve this purée as a pasta sauce, by just adding some cooked baby pasta
