Directions

1. Place pork in a large bowl and season with salt and pepper. Stir in fennel seeds. Stir in flour and set aside.
2. In a 6-quart pressure cooker** without a cooking rack over medium-high heat, warm prosciutto and olive oil. Add pork cubes and cook, stirring occasionally, until browned, 5 to 7 minutes. Add sausage, carrot, and onion and cook, stirring occasionally and breaking up sausage, for 2 minutes. Add wine and cook, scraping up any browned bits in the pressure cooker, until wine is almost entirely evaporated, 10 to 12 minutes. Stir in tomatoes, scraping up any browned bits in the pressure cooker. Stir in umami paste, cover, and bring up pressure. Cook under pressure for 25 minutes.
3. Remove from heat and let pressure drop. Release pressure and stir in parsley, sage, and rosemary. If you like, stir in butter just before serving.
