This recipe, with its bold peppercorn cream and vibrant jalapeño mint sauce, is my homage to those cherished memories, a way to bring that same joy to your table.

Ingredients

• Roast Lamb

  • 6 New Zealand lamb racks
  • 1 cup Dijon mustard
  • 3 cups Breadcrumbs
  • 1/4 lb Butter, melted

• Peppercorn Cream Sauce

  • 10 cups Beef stock (rich homemade stock is important to the rich flavor of the sauce; using canned stock will affect the)
  • 2 cups Burgundy wine
  • 2 tablespoons Brandy
  • 1/2 teaspoon Shallot, minced
  • 1 tablespoon Peppercorn, coarsely crushed (the Blue Lion uses a mixture: black, white, green, Szechuan, pink, etc.)
  • 1/2 tablespoon Fresh rosemary, chopped
  • Salt
  • 2 cups Heavy cream

• Jalapeño Mint Sauce

  • 1/2 cup Water
  • 3/4 cup Sugar
  • 2 tablespoons Green crème de menthe
  • 1 1/2 cups Fresh mint, chopped
  • 3 Fresh jalapeños, seeded and chopped
  • 1/4 cup Cold water
  • 1 teaspoon Gelatin

Equipment Needed

• Baking Sheet
• Saucepan
• Small Bowl

Instructions

1. Prepare the Jalapeño Mint Sauce: In a saucepan, combine water, sugar, and crème de menthe. Heat over medium heat, stirring constantly, until the sugar is completely dissolved.
2. Add the fresh mint and jalapeños to the sugar mixture. Bring the mixture to a boil, then reduce the heat and simmer for about 5 minutes to allow the flavors to meld.
3. In a separate small bowl, mix the gelatin with the cold water. Let it stand for a few minutes to soften the gelatin.
4. Heat the gelatin mixture gently until the gelatin is completely dissolved. Be careful not to boil it.
5. Combine the mint mixture with the gelatin mixture. Stir thoroughly to ensure the gelatin is evenly distributed.
6. Pour the mixture into a container. Refrigerate overnight to allow the sauce to set completely. This will result in a refreshing and slightly spicy mint jelly.
7. Prepare the Lamb Racks: Ask your butcher to French trim the lamb racks. This involves removing the fat cap and scraping the silverskin from the bones to create a cleaner presentation.
8. Preheat the Oven: Preheat your oven to 350°F (175°C).
9. Coat the Lamb: Brush each lamb rack generously with Dijon mustard. This will help the breadcrumbs adhere and add a tangy flavor.
10. Roll the mustard-coated lamb racks in breadcrumbs, ensuring that both the top and bottom are evenly coated. Press the breadcrumbs gently to help them stick.
11. Arrange and Butter: Arrange the breadcrumb-coated lamb racks on a baking sheet. Drizzle the melted butter evenly over the breadcrumbs. This will help them brown and crisp up during baking.
12. Bake the Lamb: Bake the lamb racks in the preheated oven for 20-30 minutes, or until they reach medium-rare doneness. Use a meat thermometer to check the internal temperature; aim for 130-135°F (54-57°C) for medium-rare. Remember that the cooking time will vary depending on the thickness of the lamb racks and your oven.
13. Prepare the Peppercorn Cream Sauce: In a large saucepan, boil the beef stock over high heat until it is reduced to 1 cup. This concentration of flavor is crucial for the richness of the sauce.
14. In a separate saucepan, combine the Burgundy wine, brandy, and minced shallots. Bring the mixture to a boil and continue boiling until it is reduced by half. This process intensifies the flavors and removes the harshness of the alcohol.
15. Add the reduced beef stock to the wine mixture. Continue to boil until the mixture is reduced to 1 cup.
16. Season the sauce with fresh rosemary and salt to taste.
17. Add the heavy cream to the sauce and cook over medium heat, stirring constantly, until the sauce thickens to your desired consistency. This may take several minutes.
18. Assemble and Serve: Before serving, stir the jalapeño mint sauce to ensure it is well combined.
19. Slice the lamb racks into individual chops. Serve the lamb chops on a bed of peppercorn cream sauce, with the jalapeño mint sauce served on the side as a dipping sauce.

Expert Tips & Tricks

• For an even richer flavor in the peppercorn cream sauce, use bone marrow in the beef stock.
• To prevent the breadcrumbs from burning, tent the lamb with foil during the last few minutes of baking if they are browning too quickly.
• Make the peppercorn cream sauce ahead of time and reheat it gently before serving.
• If you don’t have access to a wide variety of peppercorns, use a good quality mixed peppercorn grinder for the peppercorn cream sauce.
• For a beautiful presentation, garnish the lamb chops with fresh rosemary sprigs.
• To get a crispier crust on the lamb, you can broil it for the last minute or two of cooking, watching carefully to prevent burning.

Serving & Storage Suggestions

Serve the roast lamb immediately after slicing for the best flavor and texture. The peppercorn cream sauce should be served warm, and the jalapeño mint sauce chilled. This dish pairs well with roasted vegetables such as asparagus, potatoes, or carrots. A crisp green salad also makes a refreshing accompaniment.

Leftover lamb can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or in the oven. The peppercorn cream sauce can also be stored in the refrigerator for up to 3 days. Reheat gently over low heat, stirring occasionally. The jalapeño mint sauce can be stored in the refrigerator for up to a week.

Variations & Substitutions

• For a milder jalapeño mint sauce: Reduce the amount of jalapeños or remove the seeds and membranes completely.
• For a dairy-free peppercorn sauce: Use coconut cream or cashew cream instead of heavy cream. Note that this will alter the flavor slightly.
• Spice it up: Add a pinch of cayenne pepper to the breadcrumb mixture for a subtle kick.
• Herb Variations: Experiment with different herbs in the peppercorn sauce, such as thyme or tarragon.
• Lamb Cut: If you can’t find lamb racks, a boneless leg of lamb can also be used. Adjust the cooking time accordingly.
• Wine Substitution: If you don’t have Burgundy wine, you can use a similar dry red wine like Pinot Noir or Merlot.
