Instructions

1. Preparing the Fish

Start by carefully cleaning the Zander fish. Place the fish on a clean cutting board, and with a sharp fillet knife, remove the scales if present, then proceed to fillet the fish while keeping the skin intact. To do this, make a precise incision behind the gills down to the backbone, then work the knife along the backbone, gently lifting the fillet away while keeping the skin attached. Repeat on the other side of the fish.

Ensure that the fillets are free of bones by carefully removing the small pin bones with tweezers. Once filleted, cut the fish into manageable, uniform portions, approximately 150-200 grams each. These pieces should retain the skin for flavor and crispiness when frying.

Squeeze fresh lemon juice over the fish pieces and season with salt and freshly ground black pepper. Set aside to marinate briefly while preparing the broth.

2. Making the Fish Broth

In a large saucepan, combine the fish bones (if you have the head or trimmings), leek stalk, onion, celery, black peppercorns, and ¾ liter of water. Bring the mixture to a gentle simmer over medium-high heat. As the foam rises, skim it off to keep the broth clear and clean-tasting.

Reduce the heat slightly and allow the broth to simmer slowly for approximately 45 minutes to 1 hour, ensuring maximum flavor extraction. During this time, you can occasionally skim off impurities or scum that surface.

Once the broth has developed a rich aroma and flavor, strain it through a fine sieve or cheesecloth into a clean saucepan, discarding the solids. Return the clear broth to the stove and reduce it to approximately ¼ liter by simmering gently, which concentrates the flavors.

3. Preparing the Beans and Vegetables

While the broth is reducing, prepare your beans. Trim the ends and cut into small, oblique pieces to ensure an attractive, skewed appearance. Blanch the beans in boiling salted water for about 5 minutes, then drain and set aside.

In a frying pan, cook the diced bacon over medium heat until crispy. Using a slotted spoon, transfer the bacon to a paper towel-lined plate to drain excess fat. In the same pan, add the diced shallots and sauté in the rendered bacon fat until translucent and fragrant, about 2-3 minutes.

Add the blanched beans to the shallots and bacon fat, stirring gently to combine and warm through. Keep warm on low heat until ready to serve.

4. Making the Sauce

In the saucepan with the reduced fish broth, stir in the coarse mustard. Whisk continuously to incorporate the mustard evenly, creating a smooth, flavorful base.

Gradually add the small pieces of cold butter, one by one, whisking constantly to emulsify the sauce and achieve a glossy texture. This process is crucial for richness and stability, ensuring the sauce coats the fish and vegetables beautifully.

Once the butter is fully incorporated, gently fold in the whipped cream, stirring carefully to blend the sauce into a creamy finish. Adjust seasoning with additional salt, pepper, or lemon juice if necessary. Keep the sauce warm but do not let it boil, as this can cause separation.

5. Cooking the Fish

In a clean frying pan, heat the oil over high heat. Place the fish fillets skin-side down and fry for approximately 2-3 minutes until the skin becomes crisp and golden. To prevent the skin from curling, score it crosswise with shallow cuts before frying.

Turn the fillets and cook briefly on the flesh side, only about 30 seconds, until just cooked through. The fish should be tender and flaky, not overdone. Use tongs or a fish spatula to handle the fillets gently, preserving their integrity.

6. Assembling the Dish

Arrange a bed of the prepared beans and vegetables in the center of each plate. Ladle the hot, velvety sauce over the beans, ensuring they are well coated and visually appealing.

Place the fish fillets atop the bean bed, skin-side up if desired for presentation. Garnish with a few fresh herbs or additional lemon wedges for added flavor and visual contrast.

Preparation Tips

• Fish Handling: Keep fish on ice until ready to fillet to maintain freshness. Use a very sharp knife for clean cuts, and handle the fish gently to prevent tearing.
• Broth Clarity: Skimming impurities during simmering ensures a clear, refined broth, essential for elegant presentation.
• Sauce Emulsification: Add cold butter gradually; if the sauce looks curdled, whisk vigorously or briefly reheat gently to restore smoothness.
• Fish Cooking: Do not overcook fish; it continues to cook slightly after being removed from heat, so take it off just before it reaches the desired doneness.

Nutritional Information

Tips and Tricks

• Fish Fillet Handling: Keep the fish cold and work quickly to prevent the flesh from becoming too soft or tearing.
• Broth Intensity: Reducing the broth carefully concentrates flavor, so don’t rush the simmering process.
• Emulsifying Sauce: For an even creamier sauce, maintain a gentle simmer during butter incorporation, and stir continuously.
• Fish Crispy Skin: Score the skin to prevent curling and ensure even crisping.
• Presentation: Use a shallow bowl or a wide plate to showcase the colorful beans and the gleaming fish fillets.

Add-ons and Variations

• Herbs: Fresh dill, parsley, or chervil add brightness and freshness. Sprinkle over the finished dish.
• Additional Vegetables: Incorporate sautéed mushrooms, roasted cherry tomatoes, or wilted spinach for extra layers of flavor.
• Vegan Version: Replace fish with hearty vegetables like eggplant slices or tofu, and use plant-based creams and broths.

Side Dishes

Complement this dish with boiled new potatoes, crusty artisanal bread, or a light green salad dressed with vinaigrette. These options enhance the meal’s freshness and make it more filling.

Improvements

• Flavor Depth: Roasting bones or fish heads beforehand adds a depth of flavor to the broth.
• Texture Contrast: Serve with crispy potatoes or toasted baguette slices for texture variation.
• Presentation: Garnish with microgreens or edible flowers for an elegant presentation.

Save and Store

Leftover fish and beans can be stored separately in airtight containers in the refrigerator for up to 2 days. Reheat gently in a microwave or oven to prevent the fish from drying out. The sauce can be refrigerated for up to 3 days but may need whisking or reheating gently to restore its consistency.

FAQ

Can I substitute the fish with another type?

Yes, firm white fish like cod, haddock, or halibut can be excellent alternatives. Adjust cooking times accordingly based on thickness and texture.

How do I ensure the fish skin stays crispy?

Score the skin, dry it thoroughly before frying, and ensure the oil is hot enough (around 180°C/356°F). Do not overcrowd the pan to maintain high heat and crispiness.

Is there a vegetarian version of this dish?

Implement plant-based ingredients such as hearty mushrooms or eggplant in place of fish, use vegetable broth, and omit the dairy or use plant-based creams for a vegetarian adaptation.
