I decided last week i wanted to try a few new veg and fruit that ive never tried or cooked with before… and here we come to my dilemma.

i have sweet potato and i CANNOT get them to go crispy in the oven
I have tried par boiling, not par boiling, cooking them for 45 mins, higher temp and the list goes on. I even tried usin a potato chipper – needless to say that didnt work and nearly injured myself lol

Anyways just wondered if anyone would be my kitchen fairy and had a solution for me?

Thanks in advance
