Instructions
- Step 1: Heat the sunflower oil and butter together in a deep frying pan over medium heat until the butter is foaming.

Tips & Variations
- Use fresh peas when in season for the best sweetness; frozen peas work well too if fresh are unavailable.
- Choose a dry cider or a crisp white wine to add bright acidity that balances the richness of the butter.
- For extra color and freshness, add chopped fresh herbs like parsley or chives along with the pea shoots.
Storage
Best enjoyed immediately, this dish does not store well due to the delicate fish and mussels. If you have leftovers, refrigerate in an airtight container for up to 24 hours and gently reheat in a pan over low heat, avoiding overcooking.
