Cut the cod into large chunks and place them on a baking tray lined with baking paper. Drizzle with olive oil and season well with salt and pepper. Set aside — don't bake yet, wait until the soup is ready.

Pour in the fish stock and bring to a boil. Lower the heat and let it simmer for 3–4 minutes until the broccoli is tender. Add the peas and cream and bring back to a boil.

While the soup is going, halve the red onion and slice it thinly. Mix together the vinegar, sugar, and water, then toss the onion in and let it sit until you're ready to serve.
