I really miss winter in my hometown. Sweet memory of roasted sweet potato and candied fruit on the stick. The traditional kind of roasted sweet potato is done by a simple and crude oven made from a big iron container. The stall owners would separate the container into 2 parts. One is to be filled with charcoal and the other one is for the rack to put the sweet potatoes. Freshly-roasted and oil-dripping sweet potatoes are hidden there.
It’s quite easy to make it at home with oven. The thin type is easy to cook and will taste better.
Preheat oven to 230 Degree C.
Put sweet potatoes into the oven and bake for 40-50 mins. Flip in the half way.
