Method

    1. Heat oil in a large saucepan over medium heat; add onion, parsley and garlic; sauté for 5 minutes or until fragrant. Add sake, scraping any caramelisation from the bottom of the pan; bring to the boil and simmer until reduced by half. Add water, parmesan and kombu and simmer for 2 hours or until reduced by half; stir occasionally to ensure parmesan doesn’t stick to the bottom of the pan. Strain and set aside to cool.


    2. Meanwhile, for the gnocchi, set the steam oven to 100°C; add potatoes to a large perforated tray and steam for 30 minutes or until tender; set aside to cool


    3. Peel and cut the potatoes and pass through a ricer. Or you can cool completely and mash really fine with a large fork, ensuring there are no large chunks.


    4. Place flour and salt on a work surface; combine potato and egg in a bowl and mix well; tip onto the flour and slowly start to combine using your hands to build a mass of dough. Keep adding extra flour as needed to prevent it from sticking to your hands and table. Don’t overmix or gnocchi will toughen.


    5. Once a smooth dough is achieved, divide into four pieces and roll each piece into a long rope about 2.5cm thick. With a sharp knife, cut into small pieces and place onto a tray covered with baking paper. Sprinkle with flour to prevent sticking.


    6. For the leek oil, place leek scraps, garlic and oil in a medium saucepan over medium low heat; cook, stirring occasionally, for 15 minutes or until leeks soften, garlic lightly caramelises and flavours infuse. Strain and set aside.


    7. Heat up the broth in a small pot over medium heat and set another sauté pan on low with about 1-2 tablespoons butter.


    8. Bring a large pot of salted water to the boil; add gnocchi in small batches. Too many will lower the temperature of the water, causing them to get soggy. Once they start to float to the surface, remove with a slotted spoon and place into the sauté pan; lightly coat the gnocchi in butter and cook for 1 minute until lightly brown. To serve, divide gnocchi between eight bowls; pour over some broth and finish with a small drizzle of leek oil, grated parmesan, some spring onions and freshly ground black pepper.
