This cake is inspired by the scent of the gorse bushes along the Lizard peninsula in Cornwall, where my family and I go walking on summer holidays. The scent can be elusive, but occasionally, on a warm, sunny day, the breeze catches those golden flowers and diffuses their distinct, sweet scent – a mingling of coconut, vanilla and almond. I’ve added lime to freshen things up, should those flavours prove a little heady or rich.
