Fish Pate

Directions

1. Start by prepping the marinade in a shallow dish: whisk together the shallots, lime juice, white wine, thyme sprigs, bay leaf, olive oil, a pinch of salt, and black pepper. Add the trout fillets, ensuring they’re fully coated. Cover and let them chill in the fridge for 1 hour to soak up those zesty flavors. This step infuses the fish with brightness, but don’t marinate longer or it might turn mushy.
2. After marinating, remove two fillets and set them aside whole. These will be your terrine’s centerpiece for that satisfying texture contrast. Pat the rest dry, then grind them finely in a food processor or meat grinder. If using a processor, pulse in batches to avoid overheating.
3. In a small skillet over medium heat, cook the ground fish gently in the marinade liquid until just opaque, about 6 minutes. Stir occasionally to prevent sticking. Scoop out the fish with a slotted spoon, then simmer the marinade on its own until reduced by half, about 5-7 minutes. Set both aside to cool slightly. This concentrates the flavors without overcooking the delicate trout.
4. Now, make the panade base: in a medium saucepan, heat the milk, 3 ounces butter, and a pinch of salt until simmering. Dump in the flour all at once and stir vigorously with a wooden spoon over medium heat until it forms a smooth ball that pulls away from the pan sides, about 2 minutes. Remove from heat and let cool for 5 minutes.
5. Beat the egg yolks into the panade one at a time, mixing well after each until glossy and incorporated. This binds everything without scrambling the eggs, keeping your mixture velvety.
6. Time to build the mousse in the food processor: start with ¼ cup ground fish and pulse to smooth. Add ¼ cup panade and one ice cube, pulsing again. Alternate adding the remaining ground fish, panade, and ice cubes in small batches, pulsing each time. Halfway through, add the 4 whole eggs and remaining egg yolk for extra richness.
7. Season the mixture with salt, pepper, cayenne, and nutmeg. With the processor running, slowly drizzle in the cream until emulsified. Fold in the chopped tarragon and any remaining softened butter by hand for a final burst of herb aroma. Taste and adjust seasonings. If it seems too loose, chill briefly.
8. Preheat your oven to 350°F (180°C). Grease a 1.5-quart terrine mold or loaf pan with butter and line with buttered parchment paper (old butter wrappers work great for nonstick magic). Spoon in half the mousse mixture, smooth it out, then lay the reserved whole fillets lengthwise on top. Cover with the remaining mousse and tap the pan gently to release air bubbles.
9. Place the terrine in a larger baking dish and pour hot water halfway up the sides for a gentle bain-marie bake. Slide into the oven and cook for 45 minutes, or until puffed, golden on top, and a skewer inserted comes out clean. Let cool in the water bath for 10 minutes, then unmold onto a platter. Trim edges if needed, slice, and serve warm or chilled.
10. For the sauce: If using whole crabs, chop them roughly (shells and all for flavor). Melt 2 ounces butter in a saucepan over medium heat, add shallots, thyme, and parsley, and sauté until fragrant, about 2 minutes. Toss in the crabs and cook until they brighten in color, about 5 minutes.
11. Pour in the white wine, salt, pepper, cayenne, and cream. Bring to a boil, add the bay leaf, then reduce heat and simmer until thickened, about 10 minutes. Strain through a fine mesh sieve into a clean pan, pressing solids to extract every drop. Simmer again until it reaches whipping cream consistency, about 5 more minutes. Adjust seasoning and serve warm alongside terrine slices.
