• ¼ cup / 60ml fish sauce
• 2 tbsp / 28g butter

Instructions

2. Ensure your mussels are thoroughly rinsed and cleaned. Place them directly into the inner pot of your pressure cooker.
3. Sprinkle the mussels with Italian seasoning and stevia powder. Add the chopped cherry tomatoes and pour in the fish stock.
4. Secure the lid and set the steam release handle to the ‘Sealing’ position. Select the ‘Manual’ or ‘Pressure Cook’ button and set the timer for 1 minute.
5. When the cooking is complete, perform a quick pressure release by carefully moving the handle to the ‘Venting’ position.
6. Once the pin drops, open the lid. Stir in the butter and fish sauce until the butter has melted, creating a rich, savory broth.
7. Ladle into bowls and serve immediately, optionally garnished with freshly chopped parsley.
