sweet potato fries

I am a big fan of sweet potato fries. I never had them before I moved down south and now I'm addicted. The problem is that they always come out overcooked so I always ask for them to be brought out undercooked. No one ever listens until tonite. At Duke's they listened and I had perfect sweet potato fries sprinkled with brown sugar - delightful; manna from heaven. Yummy, yummy, yummy.
