Sunchoke Soup with a Proscuitto Croissant
Ingredients
2 white onions, small diced
1 celery heart, finely diced
1 leek (white part only), washed and finely chopped
100 g salted butter
400 g sunchokes, peeled, finely chopped and soaked in milk
Salt and white pepper to taste
11⁄2 cups (350 ml) chicken stock
11⁄2 cups (350 ml) hot milk
Puff pastry
Prosciutto slices
Grainy mustard
Egg wash
Preparation
- In a medium stockpot on moderate heat, sweat the vegetables in the butter until translucent, lightly seasoning with salt
- Add the sunchokes and sweat for two more minutes
- Add stock just to cover the vegetables and turn up heat to high
- Cook for 20 minutes until the sunchokes soften
- Transfer to a blender and blitz on high for one minute (break up into smaller batches if necessary). Season to taste and pass through a sieve before serving
- Preheat oven to 350 degrees F
- On a lightly floured surface, roll out the pastry to 2-3 mm thick
- Cut out triangles 10 cm high to a 7.5 cm diameter base
- Brush with grainy mustard and egg wash. Top with a slice of prosciutto
- Roll up croissant from the base to the tip, and brush more egg wash on top
- Bake in oven on a greased, lined tray until golden and crispy (approximately 20 minutes)
- Serve on top of soup as garnish
Croissant
Note: Always bake puff pastry from cold as the butter will stay incorporated in the pastry during baking, allowing an even, crispy finish
