I fell in love with Sweet Potato Fries when we toured the Southern States of America last year.  They were as ubiquitous as normal potato fries and I had them in heaped generously into baskets at a blues club with a ginormous burger. Later on at the Bluebird café, whilst female songwriters and their guitars poured their hearts out to an intimate crowd I scoffed sweet potato fries.

I have made and eaten sweet potato fries many times but nothing compared to those fries I ate in America.  At home they generally get a bit soft in the oven, refuse to crisp, stick to the pan and clump together to form more of a sweet potato mess.  Delicious but not really ideal for dipping. So it became my mission to perfect my favourite chip and get them as uniquely crispy as I know they could be.

How do you make perfect Sweet Potato Fries?

  1. Soak the cut potatoes in cold water for 1 hour to get rid of all the starch. 
  2. Pat dry with kitchen towel and place in the fridge for 1 hour to completely dry out.
  3. Toss the fries in cornflour before you bake to encourage the moisture out of the chip. 
  4. Bake on parchment paper or a silicone sheet as well as these fries love to weld to the baking tray otherwise.
