For the egg-nest pasta:
Knead the soft-wheat flour, semolina, salt, and gold-spun yolks until they coalesce into a smooth, harmonious dough. Let it rest in quiet contemplation for at least 30 minutes.

For the venison farce:
Sear the venison stew meat in extra virgin olive oil to whisper its juices shut. In the same vessel, introduce the onion, carrot, juniper berries, red wine, red miso, and tomato concentrate. Cover with water and let it simmer over a whisper of a flame for at least 6 hours. Alternatively, let it braise in a pressure cooker for approximately 1 hour and 30 minutes. Reduce the cooking jus, discard the juniper berries, and gently shred the meat by hand, uniting it once more with the reduced jus. Adjust with salt and pepper. Shape into elegant 10g spheres and let them firm in the chill of the refrigerator for at least 4 hours.

For the tortelli:
Roll the dough to a gossamer thinness and cut into delicate discs. Place a 10g sphere of the rich farce upon the center of each, folding them into the classic, sculpted shape of the tortello.

For the broth:
Sliver all the vegetables. Toss with a whisper of salt and a thread of extra virgin olive oil. Lay them upon a tray to dry in the oven at 150 °C for about 50 minutes, turning them occasionally to capture the heat evenly. Transfer the dried vegetables to a pot with 1 liter of pure water and the sheet of kelp. Simmer gently for 1 to 1.5 hours, then strain and adjust with salt. The resulting elixir should be lightly fluid, just infinitely richer than a simple broth.

For the Tuscan kale oil:
Flash-fry the Cavolo Nero at 160 °C in sunflower oil and allow it to cool. Blend it with the extra virgin olive oil and a pinch of salt, then let the mixture rest in the freezer for about 1 hour. Strain to capture the vibrant, emerald-hued oil.

For the final assembly:
Cook the ravioli for 3-4 minutes, toss them gently in rich butter, and arrange them at the center of the plate. Pour the warm broth over them and adorn with a few droplets of the vibrant kale oil.
