Recipe is by Brad Leone. Brad learned by accident one day. He was done roasting a batch of these naturally sweet, starchy root vegetables when he noticed that they weeped liquid in the oven. So he put some of those bad boys in a cheesecloth,squeezed really hard,and wound up with enough orange hued liquid to reduce in a saucepan until it was the thick,creamy texture and deep color of caramel.
1Preheat heat oven to 425 degrees. Place chopped potatoes and ½ cup of water into a 9"x13" baking dish,covered with foil. Bake for 1 hour covered and 15 minutes uncovered. Remove dish from oven and add remaining half cup of water to loosen up any bits in the baking dish.
2Place all the solids and liquids into a strainer lined with cheesecloth. Let drain into a saucepan and cool for 30 minutes. Once cool enough to handle,squeeze as much liquid out from the potatoes in cheesecloth as possible. You should end up with a cup and a half of liquid.
3In a saucepan,bring the sweet potato liquid to a boil,then reduce heat for a steady simmer. Allow the liquid to reduce for 15–20 minutes until it starts to thicken and starts to form a caramel. Stir often in the final minutes.
4If you wanted to, you could add a little butter and sugar to sweeten it up even more. Pour into a jar and in store the refrigerator for up to 2 weeks. Can be served with roast meats or as a sauce over ice cream or brownies. Oh, and don’t forget to eat the leftover sweet potato mash!
