This recipe involves par-boiling the the potatoes first before roasting, so they all cook evenly and are fluffy on the inside and crispy on the outside.
Make sure the potatoes are really dry after par-boiling them for 10 minutes. This will prevent them from sticking to the tin as they roast.
Delicious...I like to think my roasties now rival my dad's in terms of deliciousness! - 10 Aug 2013 (Review from Allrecipes UK & Ireland)

Until yesterday, I had never heard of "Roasties". (A fault of being hidden deep in the USA.) I did learn they are a UK recipe so I jumped across the pond to get a recipe. I am very happy that this is the one I chose for the first try. The roasties turned out crispy and golden outside, yet fluffy and moist inside. I will not pursue any other recipe for roasties. Thank you, Ita! - 18 Mar 2017 (Review from Allrecipes UK & Ireland)
