    Beetroot Recipes

    Beetroot Hummus
    Beetroot is one of those vegetables that seems to quickly build into gluts.

    There's only so much you can pickle or bake, before you start to get bored.

    So here's a quick and nutritious recipe to use up cooked beetroot and add a new twist to a traditional dish.

    Hummus is a staple of Middle Eastern cookery. Its blend of chick peas and sesame seeds are a valuable source of calcium, protein, vegetable fats, iron and B vitamins. The addition of beetroot increases the vitamin C content and adds magnesium. All of which combines to make this pretty much a super-food.

    The pretty pink colour makes it fun for kids, so you might even be able to persuade little ones to eat this on toast or with fresh veg sticks!

    You can either make this from scratch, with dried chick peas and fresh beetroot or you can whiz it up in 5 minutes using pre-cooked beetroot and a can of chick peas / frozen chick peas.

    Pink Mash
    This recipe for beetroot pink mash is vibrant, packed with nutrients and really tasty. It's a great way to experiment with fresh beetroot. Why not give it a go? Thanks to Natasha Mangion for sending this in!

    Natasha says: "My friend Karen & I went through a stage where we were interested in Chakras and colour therapies and we used to experiment with what we called 'Chakra Cooking'. This recipe is both fun and Very colourful and really gets you in touch with your Base Chakra which is Red.

    I just like it because it's an interesting way to liven up mashed potato and it really looks striking!! Nice and bright on those dark winter days!

    It's also a great way to get kids to eat veg."

    This fabulous combo was sent into us by Karina L in New Zealand. Karina says:

    Beetroot Jelly
    This recipe was sent into us by Carole L, who says

    "Beetroot Jelly was created as a posh picnic accompaniment when a group of us used to go every summer to the outdoor theatre at Hever Castle. One of us would take a whole cooked salmon whilst the other eleven had to produce an unusual side dish!"

    Baked Beetroot
    This recipe is best done with baby beetroots, whilst they're nearer the size of golf balls than tennis balls. They cook more quickly and taste sweeter.
