• 3 largeEggs (about 150 g without shells)
• 120 gPlain yogurt (full-fat preferred for tenderness)
• 120 mlHeavy cream (for a smooth, airy terrine)
• 20 gCornstarch (about 2 tbsp; stabilizes the mousse)
• 350 gFresh mushrooms (cremini or white; wiped clean and thinly sliced)

Instructions

1. 1

   Bloom the saffron: grind saffron threads to a powder, then stir with 30 ml hot water. Cover and steep 10 minutes. Meanwhile, grease a 1.5–2 liter loaf pan or terrine mold with 10 g butter and line it with parchment (base and long sides) for easy unmolding. Preheat the oven to 160°C (320°F).

2. 2

   Cook the mushroom layer: heat 30 g butter with 15 ml olive oil in a wide skillet over medium-high heat. Add sliced mushrooms and cook 8–10 minutes, stirring, until their liquid evaporates and edges turn golden. Stir in dill and parsley for 30 seconds. Season with 2 g salt and 0.5 g pepper from the measured amounts, then cool to room temperature (about 15 minutes).

3. 3

   Make the chicken mixture: in a food processor, add chicken pieces, grated onion (well-squeezed), garlic, remaining salt (8 g), remaining pepper (1.5 g), lemon juice, bloomed saffron (all liquid), eggs, yogurt, cream, and cornstarch. Process 60–90 seconds, scraping once, until very smooth and slightly fluffy. Keep the mixture cool; if it warms, refrigerate 10 minutes before molding.

4. 4

   Assemble the terrine: spread one-third of the chicken mixture into the prepared mold, tapping firmly to remove air pockets. Add half the cooled mushrooms in an even layer, keeping a 1 cm border from the edges. Sprinkle pistachios evenly if using. Add another third of chicken mixture, then the remaining mushrooms, and finish with the last third of chicken mixture. Smooth the top and tap the mold 8–10 times.

5. 5

   Bake gently in a water bath: place the mold in a deep roasting pan. Pour boiling water into the roasting pan to come halfway up the sides of the mold. Bake at 160°C (320°F) for 55–65 minutes, until the center reaches 74°C (165°F) on a probe thermometer and the top feels set but springy.

6. 6

   Rest, chill, and slice: remove the mold from the water bath and cool on a rack 30 minutes. Cover and refrigerate at least 6 hours (preferably overnight) to set for clean slices. Unmold by lifting parchment, then slice with a hot, dry knife into 1.5–2 cm slices. Serve chilled or let stand 15 minutes for fuller aroma.
