Ingredients

For soup

  • 1 onion small (1 small onion giving around 1 ½ cups chopped)
  • 1 clove garlic small, optional
  • 18 oz Jerusalem artichokes sunchokes, approximately
  • 3 tablespoon butter or oil, if you prefer
  • 4 cups vegetable stock or chicken stock
  • a little salt and pepper, to taste

For pangrattato (crumb topping)

  • 2 slices bread ideally stale or at least day old
  • 1 clove garlic small
  • 2 tablespoon parsley
  • 1 tablespoon olive oil
  • 1 small lemon zest ie zest from 1 lemon

Instructions

To make soup

  • Peel and cop the onion in a medium dice. Peel and finely chop the garlic, if using.
  • Prepare a bowl with cold water and set beside you while you prepare the Jerusalem artichokes. Peel the Jerusalem artichokes and cut them into medium-small chunks. As soon as you have peeled and chop one, place the pieces in the bowl of water then move onto the next piece.
  • Once all the vegetables are ready, warm the butter in a heavy-based pot/pan large enough to hold all of the vegetables and stock over a medium heat. Add the onion and cook for a couple minutes so that the onion softens and becomes tranlucent.
  • Add the garlic and Jerusalem artichokes and stir, ensuring they are well coated in the butter. Cover and leave to sweat/cook for around 3 - 4 minutes.
  • Add the stock, cover and bring to a simmer. Once simmering, reduce the heat and continue to simmer for around 20 minutes until the Jerusalem artichokes are tender. Meanwhile, make the pangrattato/crumb topping.
  • Meanwhile, make the pangrattato/crumb topping.

To make pangrattato/crumb topping

  • Remove the crusts and break up the bread into medium breadcrumbs (they don't need to be very fine). Finely chop the garlic and chop the parsley.
  • Warm the olive oil in a skillet over a medium heat and add the garlic. Cook briefly, for only around a minute, just to soften and bring out the fragrance but don't let it burn.
  • Add the breadcrumbs and toast for a few minutes until the crumbs are dry and lightly browned all over, stirring and turning regularly.
  • Remove the crumbs from the heat and mix through the parsley and lemon zest. Set aside while you finish the soup.

To finish and serve

  • Once the Jerusalem artichokes are soft, remove the soup from the heat and blend until smooth. You can either use an immersion/stick blender in the pot or transfer to a blender if needed. Adjust the seasoning with a little salt and pepper, as needed.
  • Serve the soup, topped with the pangrattato/crumb topping (only add right before eating and if you like, a little at a time).
