Grilled nectarines or peaches may be one of life’s greatest joys. Cook them under the grill or a barbeque. Choose ones that are fragrant, with flesh that yields a bit when pressed gently. If a nectarine has cuts or tan spots, or if it’s rock-hard or mushy, don’t buy it. The secret to this beautiful summery dessert is the combination of flavours and textures – sweet, juicy nectarines, crunchy pistachio brittle and thick, creamy Greek yogurt. Heaven.
