Cut a sheet of baking paper to fit the base of a char-grill pan. Lightly spray or brush the pan with oil to grease. Press the baking paper into the pan and preheat on medium-high heat.
Place sugar onto a plate. Press the cut-side of peaches into the sugar to lightly coat. Place peaches sugar-side-down into the pan and cook for 2-3 minutes until golden and charred then turn and cook for a further 1 minute. Transfer peaches to a board or platter and set aside to cool slightly.
Serve peaches with coconut sour cream and honey.
