Next, he said to "chuff it up until it’s kind of a bit frosty on the outside" before choosing your chosen fat.
Then it’s about adding some herbs and flavours, with Jamie specifically calling out rosemary and garlic. It’s here that you "roast it until lightly golden and then squash it" to give it "more surface area."
And then comes the secret ingredient, the "spritz of good good vinegar" before popping them back in the oven until they’re golden crisp.
In Jamie’s own words, you should have the "best roast potatoes ever."
