Why it works: Broccoli and asparagus match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 123 recipes mention both. Both carry 2-hexenal, which smells green, leafy. The science ↓

Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Finely chop the shallot, garlic, chervil, parsley, tarragon, mint and basil. Put them in a bowl with the finely grated zest of the lemon, the juice of half the lemon and 3 tbsp extra virgin olive oil to make a salsa verde.
Trim the broccoli and asparagus into bite-sized pieces. Thinly slice the radishes and spring onions, keeping the green tops separate. Cut the Jersey Royals in half if not already done.
Melt the 50g butter in a large saucepan over medium heat. Add the shallot and white parts of the spring onions and soften for 3 minutes without browning.
Pour in the chicken stock and bring to a simmer. Add the Jersey Royals and cook for 12 minutes until nearly tender.
Add the broccoli and asparagus and cook for 3 minutes. Add the peas and cook for 2 more minutes until all the vegetables are tender. Blend roughly with a stick blender, leaving some texture.
Cut the sourdough into cubes. Heat the rapeseed oil and 1 tbsp of the remaining butter in a frying pan over medium heat and fry the bread for about 4 minutes, stirring, until golden and crisp.
In a small pan, melt the last 1 tbsp butter over medium-low heat. Add the cooked langoustines and warm gently for 2 minutes until heated through.
Ladle the soup into warm bowls. Drizzle with the remaining 2 tbsp olive oil, top with the langoustines, sliced radishes, spring onion greens and croutons, and spoon over the salsa verde before serving.

Fit is the average pairing score against chicken, butter, onion, broccoli, peas, asparagus, shallot. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
