Cauliflower Soup With Seared Scallops, Lemon Oil and Caviar

The first time I tasted this soup, it was a revelation. I was a young line cook, intimidated by the elegant, hushed atmosphere of the restaurant. Then, a bowl of this creamy, ethereal soup appeared. The simple elegance of the cauliflower, the sweetness of the seared scallops, the salty pop of caviar, and the bright zing of lemon oil… it was a symphony of flavors and textures that awakened my palate and ignited my passion for sophisticated cuisine. It transformed my understanding of what a simple soup could be, forever etching this dish in my culinary memory.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 30 minutes
• Total Time: 1 hour
• Servings: 6
• Dietary Type: Gluten-Free (optional)

Ingredients

• 3 tablespoons vegetable oil, divided
• 1 cup white onion, chopped
• 1 garlic clove, sliced
• 3 3/4 cups cauliflower (from 1 large head)
• 1 1/2 cups low sodium chicken broth (vegetable broth for vegetarian option)
• 1 1/2 cups whipping cream (or coconut cream for a dairy-free alternative)
• Kosher salt
• Fresh ground white pepper
• 1 leek, cut into 1/8-inch-thick rounds (white and pale green parts only)
• 6 sea scallops, patted dry
• 1 (30 g) jar black caviar, like American white sturgeon (about 1 ounce) – optional
• 6 teaspoons lemon-infused olive oil
• Fresh chives, finely chopped

Equipment Needed

• Heavy large saucepan
• Blender
• Small saucepan
• Medium skillet

Instructions

1. Heat 2 tablespoons of vegetable oil in a heavy large saucepan over medium heat. Add the chopped white onion and sliced garlic clove. Sauté until the onion is soft and translucent, about 5 minutes. Be careful not to brown the garlic, as it can become bitter.

2. Add the cauliflower florets, low sodium chicken broth, and whipping cream to the saucepan. Bring the soup to a boil, then immediately reduce the heat to low. Partially cover the saucepan and simmer gently until the cauliflower is very tender and easily pierced with a fork, about 18 minutes.

3. Carefully transfer the soup in small batches to a blender. Puree until completely smooth. If you don’t have a blender, you can use an immersion blender directly in the saucepan. Be extremely cautious when blending hot liquids to avoid burns; vent the blender lid slightly to allow steam to escape.

4. Return the pureed soup to the same saucepan. Season generously with kosher salt and fresh ground white pepper. Taste and adjust seasoning as needed.

5. Do Ahead: At this point, the soup can be made up to 1 day ahead. Allow the soup to cool slightly, then cover and chill thoroughly in the refrigerator. Reheat gently over low heat before serving, stirring frequently.

6. Blanch the leek rounds in a small saucepan of boiling salted water for 1 minute. This softens the leeks and mellows their flavor. Immediately drain the leeks in a colander.

7. Heat the remaining 1 tablespoon of vegetable oil in a medium skillet over high heat. Ensure the skillet is very hot before adding the scallops for optimal searing.

8. Sprinkle the sea scallops generously with salt and pepper. Place the scallops in the hot skillet, making sure not to overcrowd the pan; work in batches if necessary. Sear until deeply golden brown and just opaque in the center, about 1 1/2 minutes per side. Avoid overcooking, as scallops become rubbery when overdone.

9. To assemble, place some of the blanched leek rounds in the center of each soup bowl. Place 1 seared scallop on top of the leeks in each bowl. If using, top each scallop with a small dollop of black caviar.

10. Ladle the hot cauliflower soup carefully around the scallop, leaving the scallop visible. Drizzle each bowl with 1 teaspoon of lemon-infused olive oil and sprinkle with finely chopped fresh chives. Serve immediately.

Expert Tips & Tricks

• For an even smoother soup, strain the pureed soup through a fine-mesh sieve before returning it to the saucepan.
• If you can’t find lemon-infused olive oil, you can make your own by steeping lemon zest in good quality olive oil for a few days.
• To ensure a perfect sear on the scallops, pat them very dry with paper towels before cooking. Excess moisture will prevent them from browning properly.
• If the soup is too thick, add a little more chicken broth or cream to reach your desired consistency.
• For a richer flavor, roast the cauliflower florets in the oven with a little olive oil, salt, and pepper before adding them to the soup.

Serving & Storage Suggestions

Serve this soup immediately after assembling to enjoy the contrast between the hot soup and the slightly cooler scallops and caviar. The soup is best enjoyed fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently over low heat, stirring occasionally. The seared scallops are best consumed immediately and are not recommended for reheating. The caviar should be added just before serving.

Variations & Substitutions

• Vegetarian/Vegan: Substitute vegetable broth for the chicken broth and use coconut cream instead of whipping cream. Omit the scallops and caviar entirely, or replace the scallops with sautéed oyster mushrooms for a similar texture.
• Dairy-Free: As mentioned above, coconut cream works beautifully as a dairy-free alternative. You can also use cashew cream for an even richer, creamier texture.
• Spicy: Add a pinch of red pepper flakes to the soup while simmering for a touch of heat.
• Seasonal: During the fall, consider adding roasted butternut squash or sweet potato to the soup for a warmer, sweeter flavor profile.

FAQs (Frequently Asked Questions)

Q: Can I make this soup without a blender?
A: Yes, you can use an immersion blender directly in the saucepan to puree the soup. Be careful to avoid splattering hot liquid.

Q: Can I use frozen cauliflower?
A: While fresh cauliflower is preferred for the best flavor and texture, frozen cauliflower can be used in a pinch. Be sure to thaw it completely and drain off any excess water before adding it to the soup.

Q: Is there a substitute for the lemon-infused olive oil?
A: If you can’t find lemon-infused olive oil, you can use regular olive oil and add a squeeze of fresh lemon juice just before serving.

Q: How can I make the soup thicker?
A: If your soup is too thin, you can simmer it uncovered for a longer period to allow some of the liquid to evaporate. You can also add a slurry of cornstarch and water to thicken it.

Q: Can I make this soup ahead of time and freeze it?
A: The soup base can be made ahead of time and frozen for up to 2 months. However, it’s best to add the cream and sear the scallops fresh just before serving.
