Sweet Potato & Orange Spread

Sometimes an accident leads to an invention. Today I found a Sweet Potato in my pantry getting mouldy. I cut off all the bad bits and there was about 160g good bit left. I boiled it to make 'Kimchi & Sweet Potato Salad' for lunch but I forgot about it. Sweet Potato was over-cooked and too soft for salad. Then I mashed it to make Sweet Potato Pancakes, but I changed my mind and decided to make a dip. I needed a Lemon, then I found two Oranges getting old. I ended up making this sweet paste. It is a beautiful spread which texture is similar to Lemon Curd.
