Crispy Crunchy Potato Bites

From super food magazine - I've got these ready to go in the oven at the moment though I scaled back for 4 serves and used 4 garlic cloves instead of 2 since they were very small otherwise made as per recipe. They did recommend desiree potatoes but I used carisma's (a low GI potato). Please note that after making tonight in a non-forced fan oven at 200C it took me 60 minutes to get my potatoes nicely browned though not crisp but that is Carisma potatoes, very hard to get them crisp in this sort of cooking though I have done with shallow frying them as long as they are cut as a very small dice.
