Last night I made roasted sweet potatoes. I cut then into chunks, drizzled with olive oil, and tossed salt/pepper and allspice and then roasted them at 390 for about 45min. They came out delicious but they looked.... unappealing. I was expecting them to come out golden orange with browned edges but they didn't. What could I do to roasted sweet potatoes to give them a little oomph? Recipies and suggestions welcome.
