Mellow white or yellow miso--also known as shiro or shinshu miso, respectively--add a touch of buttery-rich umami to sweet potato chunks roasted on your June Pan. Lighter misos are milder than their darker counterparts and have a subtle sweetness and nuttiness that play well with earthy sweet potatoes. Don't be tempted to substitute a darker red or brown miso here, it will be too strong. A touch of rice vinegar and soy sauce balance the flavors, creating a savory side that can moonlight as a topping for grain bowls and salads. If you only have raw sesame seeds on hand, toast them in a single layer in a dry saute pan over medium heat on the stovetop until golden brown, about 5 minutes, while the potatoes roast.
