Cauliflower is a brassica or cruciferous vegetable – also known as the cabbage or mustard family – joining the likes of broccoli, Brussels sprouts, kale and (unsurprisingly) cabbage and mustard greens. It is packed with vitamins B and C and high in fibre. Most of the UK’s cauliflowers are grown in Lincolnshire and whilst it is harvested in spring and autumn it is generally available year-round. While you’ll be most familiar with a white cauliflower, heritage purple and orange varieties are now available along with the magnificent bright green and geometric looking romanesco cauliflower.
