• 1 to 2 tablespoons of Kerala curry paste 
• 2 tablespoons of olive oil

Preparation:

• Coat your pork tenderloins with Kerala curry paste, olive oil, sweet soy sauce, and grilled spiced fleur de sel.
• Let marinate for at least 1 hour.
• Optionally, grill the tenderloins on the barbecue, or sear them for a few minutes in a pan, then place them in the oven at low temperature (70/90°C) for about 1 hour.
• Meanwhile, prepare the sauce by sautéing the onions in a drizzle of olive oil. 
  Incorporate the Kerala curry paste, sauté for about 30 seconds, then add the crème fraîche and mix until the sauce is smooth.
• Simmer for 3 to 5 minutes over low heat.
• Once your tenderloins are ready, let them rest for 10 minutes, then slice them.
• Serve hot, accompanied by vegetables or potatoes, and top with your homemade sauce.
