My favorite way of eating Satsuma-imo (Japanese sweet potato) is a simple yaki-imo (roasted sweet potato). When I was a child, there were many Yaki-imo trucks which drive around the neighborhood to sell piping hot yaki-imo out of the stone roaster in the back of the truck. It’s no longer a common site in Japan, but you can still spot these driving vendors in the winter time.
I find Roast Donabe is the best tool for roasting sweet potatoes. I’m obsessed with this! Its extra-thick body and sturdy flat lid effectively seal the moisture inside while intensely cooking the ingredients to the core, and takes the roasted sweet potato to a whole new level. The potato becomes nicely caramelized and skin comes right off. I like to put a little butter to enjoy this, but this tastes so good without anything.
