A tricky dish to do in volume, and hence, I tend to forget to make it at the restaurant, but it is easy for the home cook. An obvious friend to bacon and eggs, these lacy cakes are also good with almost any roasted meat or bird. The sweet-salty flavor and crispy texture is irresistible and appeals to those not usually fond of sweet potatoes. These hash browns are also very pretty made with a combination of starchy, yellow sweet potatoes and a little bit of orange yam. (Don't use all yams; by themselves they form a wet, dense mass, not a lacy cake. They don't have enough starch to stick together and form a crust. They do, on the other hand, try to stick to the pan.)
