Instructions

1. Cleaning the mussels

   Rinse the mussels under cold water. Scrub the shells with a brush to remove sand. Remove visible byssal threads. Place the mussels in a large dish, cover with a lightly damp cloth and put in the back of the refrigerator (≈4 °C) for 10 min.

   Time: PT10M

2. Preparing the chili oil

   Heat 200 ml of peanut oil in a small saucepan over medium heat (≈180 °C). Add the chopped smoked sweet red chilies and the 2 crushed garlic cloves. Let infuse for 5 min while stirring gently, then remove from heat and strain. Reserve the flavored oil.

   Time: PT10M

   Temperature: 180°C

3. Cutting and preparing the fries

   Wash the potatoes, cut into 1 cm thick sticks (no need to peel). Rinse quickly in cold water to remove excess starch, then dry thoroughly with a clean cloth.

   Time: PT15M

4. First fry of the potatoes (blanching)

   Heat 800 ml of oil to 140 °C. Submerge the fries in small batches for 5 min without browning. Drain with a skimmer and place on paper towels.

   Time: PT5M

   Temperature: 140°C

5. Second fry of the potatoes (golden)

   Raise the oil to 180 °C. Fry the blanched fries for 2‑3 min until golden and crisp. Drain, salt immediately with sea salt, then keep warm.

   Time: PT5M

   Temperature: 180°C

6. Cooking the mussels in marinière

   In the large pot, heat 2 tbsp neutral oil, add the sliced shallots and chopped garlic, sauté for 2 min. Pour in the white wine and water, bring to a boil. Add the mussels, cover and cook 3‑4 min over high heat until all shells open. Remove the mussels with a slotted spoon, reserve the cooking liquid.

   Time: PT10M

7. Finishing the sauce

   Reduce the cooking liquid over medium heat until it thickens slightly (≈5 min). Stir in the liquid cream, butter, Espelette pepper and adjust seasoning with salt. Simmer for 2 min, then remove from heat.

   Time: PT5M

8. Plating

   Arrange the mussels in a large shallow dish, drizzle with marinière sauce, add the fries around, drizzle with a stream of chili oil and optionally sprinkle with flax egg (or emulsified flax egg) for the final touch.

Troubleshooting

Storage

Refrigerator: Store cooked mussels in an airtight container 1‑2 days maximum.

Freezer: Not recommended for fries, they lose their texture. Mussels can be frozen for 1 month, but quality declines.

Room temperature: Do not leave at room temperature for more than 2 hours.

• Prepare the chili oil ahead and store for 1 day in the refrigerator.
• Cut the potatoes and keep them in cold water until frying.
