Remove the romanesco’s leaves and hard core. Divide into as small florets as possible.
Slice the spring onions into rings and finely chop the garlic.
Place the romanesco florets, spring onion, garlic, olive oil, sea salt, lemon juice, vegetable stock and water into a large, deep saucepan. Break the linguine in half and add to the pot. Season generously with freshly ground black pepper.
Cover the pot and bring to the boil. Remove the lid, reduce the heat and leave to reduce for +/- 8 minutes until tender and boiled dry. Stir occasionally, adding an extra splash of water if required.
Dice the Brugge Blomme. Finely chop the chervil.
Stir both into the pasta and season to taste with salt and pepper.
