👨🍳 Instructions
- 1
Prepare the rice mixture: In a large bowl, combine the cooked rice, green peas, finely diced yellow onions, minced garlic, and chopped cilantro. Mix well.
⏱️ 15 minutes - 2
Season the mixture: Add cumin, oregano, salt, and black pepper to the rice mixture. Stir thoroughly to ensure the spices are evenly distributed.
⏱️ 5 minutes - 3
Incorporate the blood: Gently pour the fresh pig blood into the seasoned rice mixture. Stir carefully until the blood is evenly incorporated and the mixture has a uniform color. Be cautious not to overmix, which can make the sausage tough.
⏱️ 10 minutes - 4
Stuff the casings: Carefully fill each prepared hog casing with the blood and rice mixture. Use a sausage stuffer or a funnel for easier filling. Do not overfill; leave about 1 inch of casing empty at the end of each sausage to prevent bursting. Tie off the ends securely with kitchen twine.
⏱️ 30 minutes - 5
Poach the sausages: Bring a large pot of water to a gentle simmer (do not boil). Carefully place the stuffed sausages into the simmering water, ensuring they are fully submerged. Poach for approximately 1 hour, or until the sausages are firm to the touch and have a deep, dark color. The internal temperature should reach 71°C (160°F).
⏱️ 1 hour - 6
Cool and prepare for grilling: Remove the poached sausages from the water and let them cool slightly on a wire rack. This allows them to firm up further.
⏱️ 15 minutes - 7
Grill the sausages: Preheat your grill to medium-high heat (approximately 200-230°C / 400-450°F). Grill the sausages for about 15-20 minutes, turning occasionally, until they are nicely browned and slightly crispy on the outside. Be careful not to overcook, as they are already cooked through.
⏱️ 20 minutes - 8
Serve: Let the Rellena rest for a few minutes before slicing and serving hot. It is often served with traditional Colombian sides like arepas, plantains, or a fresh salad.
