Also known as root-to-fruit, this trend has seen chefs such as Tom Hunt of Bristol’s Poco and Douglas McMaster of Brighton’s Silo adopt a zero-waste policy. One way to easily achieve this is using the whole vegetable in the creation of a dish, so nothing is destined for the bin. Cauliflower lends itself to this treatment really well as the leaves crisp up beautifully once roasted.



  • cauliflower 1 small, leaves trimmed off and reserved
  • olive oil 3 tbsp
  • vegetable stock 750ml
  • garlic 2 cloves, peeled
  • white pepper
  • spaghetti 450g
  • pine nuts 4 tbsp, toasted


  • Step 1

    Heat the oven to 200C/fan 180C/gas 6. Toss the cauli leaves with 1 tbsp of olive oil, season and spread on a non-stick baking tray. Roast for 10-12 minutes or until the leaf stems are tender and the leaves are a little crispy at the edges.

  • Step 2

    Break the cauliflower into florets and cut the stalk into small pieces, then put in a pan with the stock, garlic and 2 tbsp of olive oil. Bring to a simmer, cover and cook for 15-20 minutes or until the cauli and garlic are very soft.

  • Step 3

    Scoop out the cauli and garlic into a blender and blitz, adding enough cooking liquid to give a sauce the texture of double cream. Pour back into the pan and season really well with salt and white pepper.

  • Step 4

    Cook the pasta following pack instructions. Drain then toss with the cauli sauce. Serve sprinkled with the cauli leaves and pine nuts.
