Jerusalem artichoke soup with rosemary

Fresh from the organic markets Jerusalem artichokes, they are a funny looking vegetable knobbly and awkward.
The rosemary really makes this recipe. Enjoy with a La tartine baguette and a splash of extra virgin olive oil


1 kg Jerusalem artichokes
2 cups vegetable stock
1 cup whole organic milk
1/2 brown onion, diced
1 garlic clove, crushed
1 full sprig rosemary
1 tablespoons organic ghee or extra virgin olive oil
1 celery stick, sliced finely

Peel the artichokes as well as you can, and splash with extra virgin olive oil and fresh pepper, place on a baking tray and bake for 20 minutes on 170 degrees.
In a saucepan gently heat the ghee or oil and add the garlic, onion, rosemary and celery gently saute for 2-3 minutes.
Once the artichokes are golden and soft add to the saucepan alongside with the milk and stock cook for a further 20 minutes on a low to medium heat ( you do not want the soup boiling or bubbling)
Once cool, puree in and serve.
