This recipe & the following description, notes & tips come from Australian Good Taste magazine - December 2007: "Brushing the potatoes with a mixture of olive oil and melted butter gives them a golden crust. They taste great sprinkled with sea salt. Notes & tips: * Time plan tip: You can make this recipe 2 1/2 hours ahead. Transfer to a heatproof serving dish, then fifteen minutes before serving, place the dish in the oven to reheat. * The trick to crispy potatoes is parboiling them in step 1. Make sure you choose potatoes that are about the same size - this ensures they cook evenly and makes for better presentation. If coliban potatoes are unavailable, use sebago or desiree potatoes instead. * Allow 30 minutes cooling time."
