Puree tips
Be sure to peel the sweet potato deeply enough to expose the orange flesh or the purée will be stringy.If you have time, boil both types of potato whole in their skins and then peel. This will stop the potatoes absorbing water while they cook and give a lighter result. If sweet potato isn’t available, try using butternut squash or even pumpkin, but cook separately from the potato.Per Serving:
