Ingredients:

  • Fresh Mussels: 2.2 lbs / 1 kg
  • Unsalted Butter: 3 Tbsp / 45g
  • Olive Oil: 1 Tbsp / 15 ml
  • Shallots: 2 large (finely diced) / approx. 100g
  • Garlic: 3 cloves (finely minced)
  • Fresh Thyme: 2 sprigs (or 1/2 tsp dried)
  • Sea Salt and Freshly Ground Black Pepper: To taste
  • Dry White Wine: 1 cup / 240 ml (e.g., Sauvignon Blanc)
  • Flat-Leaf Parsley: 1/4 cup (roughly chopped) / 6g
  • Double Cream (Optional): 2 Tbsp / 30 ml

Instructions:

  1. Clean the Mussels: Rinse the mussels thoroughly under cold running water. Scrub off any external debris. Discard any mussels that are cracked or remain wide open when lightly tapped (the 'tap test').
  2. Debeard: Grasp the fibrous 'beard' protruding from the side of the mussel shell and firmly tug it towards the hinged end, pulling it off. Rinse again.
  3. Mise en Place: Finely dice the shallots and garlic. Have all other ingredients measured and ready, as the cooking process is very fast.
  4. Sauté Aromatics: Heat the butter and olive oil in the large pot over medium heat. Add the diced shallots and thyme sprigs. Sauté gently until softened and translucent, about 3–4 minutes. Do not brown them.
  5. Add Garlic: Stir in the minced garlic and cook for 60 seconds until fragrant. Watch carefully to ensure the garlic does not burn.
  6. Deglaze: Increase the heat to high. Pour in the white wine. Allow the wine to come to a rolling boil and reduce slightly for 1–2 minutes, allowing the alcohol to burn off.
  7. Add Mussels: Tip the cleaned mussels into the hot broth base. Season lightly with salt and pepper.
  8. Steam: Immediately cover the pot with the tight-fitting lid. Cook on high heat for 5–7 minutes. After 3 minutes, give the pot a vigorous shake (keeping the lid on) to ensure the mussels circulate and cook evenly.
  9. Finish the Broth and Serve: After 5–7 minutes, all mussels should be open. Remove the lid. If using, stir in the double cream until incorporated, then stir in the parsley. Taste the broth and adjust seasoning. Spoon the mussels and generous amounts of broth into deep bowls. Crucially: Discard any mussels that did not open.
